PTH12050W/L —12-V Input
6-A, 12-V Input Non-Isolated Wide-Output Adjust Power Module
NOMINAL SIZE = 0.87 in x 0.5 in
(22,1 mm x 12,57 mm)
Description
The PTH12050 series is the smallest non-isolated power modules from Texas Instruments that features Auto-Track™ Sequencing. Auto-Track simplifies the sequencing of supply voltages in power systems by enabling modules to track each other, or any other external voltage, during power up and power down.
Although small in size (0.87 in × 0.5 in),
these modules are rated for up to 6 A of output current, and are an ideal choice in applications where space, performance, and a power-up sequencing capability are important attributes.
The series operates from an input voltage of 12-V to provide step-down conversion to a wide range of output volt-

ages. The output voltage of the W-suffix device may set to any voltage over the adjust range, 1.2 V to 5.5 V. The L-suffix device has an adjustment range of 0.8 V to 1.8 V. The output voltage is set within the adjustment range using a single exter­nal resistor.
Other operating features include an
on/off inhibit, output voltage adjust (trim), and output over-current protection. For high efficiency these parts employ a syn­chronous rectifier output stage.
Target applications include telecom,
industrial, and general purpose circuits, including low-power dual-voltage systems that use a DSP, microprocessor, ASIC, or FPGA.

Pin Descriptions
Vin: The positive input voltage power node to the mod-
ule, which is referenced to common GND.
Vout: The regulated positive power output with respect to the GND node.
GND: This is the common ground connection for the Vin and Vout power connections. It is also the 0 VDC reference for the control inputs.
Vo Adjust: A 1 % resistor must be directly connected be­tween this pin and GND (pin 1) to set the output voltage of the module to a value higher than its lowest value. The temperature stability of the resistor should be 100 ppm/°C (or better). The set-point range is 1.2 V to
5.5 V for W-suffix devices, and 0.8 V to 1.8 V for L-suffix devices. The resistor value required for a given output voltage may be calculated using a formula. If left open circuit, the output voltage will default to its lowest value. For further information on output voltage adjustment consult the related application note.
The specification table gives the preferred resistor values for a number of standard output voltages.

Inhibit: The Inhibit pin is an open-collector/drain nega­tive logic input that is referenced to GND. Applying a low-level ground signal to this input disables the module’s output and turns off the output voltage. When the Inhibit control is active, the input current drawn by the regulator is significantly reduced. If the Inhibit pin is left open­circuit, the module will produce an output whenever a valid input source is applied.
Track: This is an analog control input that enables the output voltage to follow an external voltage. This pin becomes active typically 20 ms after the input voltage has been applied, and allows direct control of the output voltage from 0 V up to the nominal set-point voltage. Within this range the output will follow the voltage at the Track pin on a volt-for-volt basis. When the control voltage is raised above this range, the module regulates at its set-point voltage. The feature allows the output voltage to rise simultaneously with other modules pow­ered from the same input bus. If unused, the input should be connected to V
. Note: Due to the under-voltage lockout
in
feature, the output of the module cannot follow its own input voltage during power up. For more information, consult the related application note.

PTH12050 Series
Capacitor Recommendations for the PTH12050
Series of Power Modules
Input Capacitor
The recommended input capacitor(s) is determined by the 100 µF minimum capacitance and 750 mArms mini­mum ripple current rating. A 10-µF X5R/X7R ceramic capacitor may also be added to reduce the reflected in­put ripple current. This is recommended for output voltage set points of 3.3 V and higher.
Ripple current, less than 100 m equivalent series resis-
tance (ESR) and temperature are major considerations when selecting input capacitors. Unlike polymer-tantalum capacitors, regular tantalum capacitors have a recom-
mended minimum voltage rating of 2 × (max. DC voltage
+ AC ripple). This is standard practice to ensure reliability. Only a few tantalum capacitors have sufficient voltage rating to meet this requirement. At temperatures below 0 °C, the ESR of aluminum electrolytic capacitors in­creases. For these applications Os-Con, polymer-tantalum, and polymer-aluminum types should be considered.
Output Capacitors (Optional)
For applications with load transients (sudden changes in load current), regulator response will benefit from external output capacitance. The value of 330 µF is used to define the transient response specification (see data sheet). For most applications, a high quality computer-grade alumi­num electrolytic capacitor is adequate. These capacitors provide decoupling over the frequency range, 2 kHz to 150 kHz, and are suitable for ambient temperatures above 0 °C. Below 0 °C, tantalum, ceramic or Os-Con type capacitors are recommended. When using one or more non-ceramic capacitors, the calculated equivalent ESR
should be no lower than 4 m (7 m using the manufacturer’s
maximum ESR for a single capacitor). A list of preferred low-ESR type capacitors are identified in Table 2-1.
In addition to electrolytic capacitance, adding a 10-µF X5R/X7R ceramic capacitor to the output will reduce the output ripple voltage and improve the regulator’s transient response. The measurement of both the output ripple and transient response is also best achieved across a 10-µF ceramic capacitor.
Ceramic Capacitors
Above 150 kHz the performance of aluminum electrolytic capacitors is less effective. Multilayer ceramic capacitors have very low ESR and a resonant frequency higher than the bandwidth of the regulator. They can be used to reduce the reflected ripple current at the input as well as improve the transient response of the output. When used on the output their combined ESR is not critical as long as the total value of ceramic capacitance does not exceed 300 µF. Also, to prevent the formation of local resonances, do not place more than five identical ceramic capacitors in par­allel with values of 10 µF or greater.
Tantalum Capacitors
Tantalum type capacitors are most suited for use on the output bus, and are recommended for applications where the ambient operating temperature can be less than 0 °C. The AVX TPS, Sprague 593D/594/595 and Kemet T495/ T510 capacitor series are suggested over other tantalum types due to their higher rated surge, power dissipation, and ripple current capability. As a caution many general purpose tantalum capacitors have considerably higher ESR, reduced power dissipation and lower ripple current capability. These capacitors are also less reliable as they have no surge current rating. Tantalum capacitors that do not have a stated ESR or surge current rating are not recommended for power applications.
When specifying Os-con and polymer tantalum capacitors for the output, the minimum ESR limit will be encoun­tered well before the maximum capacitance value is reached.
Capacitor Table
Table 1-1 identifies the characteristics of capacitors from a number of vendors with acceptable ESR and ripple current (rms) ratings. The recommended number of capacitors required at both the input and output buses is identified for each capacitor type.
This is not an extensive capacitor list. Capacitors from other vendors are available with comparable specifications. Those listed are for guidance. The RMS ripple current rating and ESR (at 100 kHz) are critical parameters necessary to insure both optimum regulator performance and long capacitor life.
Designing for Very Fast Load Transients
The transient response of the DC/DC converter has been characterized using a load transient with a di/dt of 1 A/µs. The typical voltage deviation for this load transient is given in the data sheet specification table using the optional value of output capacitance. As the di/dt of a transient is increased, the response of a converter’s regulation circuit ultimately depends on its output capacitor decoupling network. This is an inherent limitation with any DC/DC converter once the speed of the transient exceeds its bandwidth capability. If the target application specifies a higher di/dt or lower volt­age deviation, the requirement can only be met with additional output capacitor decoupling. In these cases special attention must be paid to the type, value and ESR of the capacitors selected.
If the transient performance requirements exceed that specified in the data sheet, or the total amount of load capacitance is above 3,000 µF, the selection of output capacitors becomes more important. For further guidance consult the separate application note, “Selecting Output
Capacitors for PTH Products in High-Performance Applica­tions.

PTH12050 Series
Adjusting the Output Voltage of the PTH12050x Wide-Output Adjust Power Modules
The Vo Adjust control (pin 5) sets the output voltage of the PTH12050 product. The adjustment range is from
1.2 V to 5.5 V
for the W-suffix module, and 0.8 V to
1.8 V for L-suffix module. The adjustment method requires the addition of a single external resistor, R

, that must be connected directly between the Vo Adjust and GND pins 1. Table 2-1 gives the preferred value of the external resistor for a number of standard voltages, along with the actual output voltage that this resistance value provides. Figure 2-1 shows the placement of the required resistor.

PTH Series of Wide-Output Adjust Power Modules (12-V Input)
Features of the PTH Family of Non-Isolated Wide Output Adjust Power Modules
Point-of-Load Alliance
The PTH family of non-isolated, wide-output adjust power modules from Texas Instruments are optimized for applications that require a flexible, high performance module that is small in size. These products are part of the “Point-of-Load Alliance” (POLA), which ensures compatible footprint, interoperability and true second sourcing for customer design flexibility. The POLA is a collaboration between Texas Instruments, Artesyn Tech­nologies, and Astec Power to offer customers advanced non-isolated modules that provide the same functionality and form factor. Product series covered by the alliance includes the PTHxx050W (6 A), PTHxx060W (10 A), PTHxx010W (15/12 A), PTHxx020W (22/18 A), and the PTHxx030W (30/26 A).
From the basic, “Just Plug it In” functionality of the 6-A modules, to the 30-A rated feature-rich PTHxx030W, these products were designed to be very flexible, yet simple to use. The features vary with each product. Table 3-1 provides a quick reference to the available features by product and input bus voltage.
Table 3-1; Operating Features by Series and Input Bus Voltage
PTH12030W (26 A) products incorporate over-tempera­ture shutdown protection. All of the products referenced in Table 3-1 include Auto-Track™. This is a feature unique to the PTH family, and was specifically designed to simplify the task of sequencing the supply voltage in a power system. These and other features are described in the following sections.
Soft-Start Power Up
The Auto-Track feature allows the power-up of multiple PTH modules to be directly controlled from the Track pin. However in a stand-alone configuration, or when the Auto-Track feature is not being used, the Track pin should be directly connected to the input voltage, V (see Figure 3-1).

Application Notes
PTH Series of Wide-Output Adjust Power Modules (12-V Input)
From the moment a valid input voltage is applied, the soft-start control introduces a short time delay (typically 5 ms-10 ms) before allowing the output voltage to rise. The output then progressively rises to the module’s set­point voltage. Figure 3-2 shows the soft-start power-up characteristic of the 18-A output product (PTH12020W), operating from a 12-V input bus and configured for a
3.3-V output. The waveforms were measured with a 5-A resistive load and the Auto-Track feature disabled. The initial rise in input current when the input voltage first starts to rise is the charge current drawn by the input capacitors. Power-up is complete within 15 ms.
Over-Current Protection
For protection against load faults, all modules incorporate output over-current protection. Applying a load that exceeds the regulator’s over-current threshold will cause the regulated output to shut down. Following shutdown a module will periodically attempt to recover by initiating a soft-start power-up. This is described as a “hiccup” mode of operation, whereby the module continues in a cycle of successive shutdown and power up until the load fault is removed. During this period, the average current flowing into the fault is significantly reduced. Once the fault is removed, the module automatically recovers and returns to normal operation.
Over-Temperature Protection (OTP)
The PTH12020W and PTH12030W of products have over-temperature protection. These products have an on-board temperature sensor that protects the module’s internal circuitry against excessively high temperatures. A rise in the internal temperature may be the result of a drop in airflow, or a high ambient temperature. If the internal temperature exceeds the OTP threshold, the module’s Inhibit control is automatically pulled low. This turns the output off. The output voltage will drop as the external output capacitors are discharged by the load circuit. The recovery is automatic, and begins with a soft-start power up. It occurs when the the sensed tem­perature decreases by about 10 °C below the trip point.
Note: The over-temperature protection is a last resort mecha­nism to prevent thermal stress to the regulator. Operation at or close to the thermal shutdown temperature is not recom­mended and will reduce the long-term reliability of the module. Always operate the regulator within the specified Safe Operating Area (SOA) limits for the worst-case conditions of ambient temperature and airflow.

The power modules function normally when the Inhibit pin is left open-circuit, providing a regulated output whenever a valid source voltage is connected to Vin with respect to GND.

PTH Series of Wide-Output Adjust Power Modules (12-V Input)
Auto-Track™ Function
The Auto-Track function is unique to the PTH family, and is available with the all “Point-of-Load Alliance” (POLA) products. Auto-Track was designed to simplify the amount of circuitry required to make the output voltage from each module power up and power down in sequence. The sequencing of two or more supply voltages during power up is a common requirement for complex mixed-signal applications, that use dual-voltage VLSI ICs such as DSPs, micro-processors, and ASICs.
How Auto-Track Works
Auto-Track works by forcing the module’s output voltage to follow a voltage presented at the Track control pin. This control range is limited to between 0 V and the module’s set-point voltage. Once the track-pin voltage is raised above the set-point voltage, the module’s output remains at its set-point regulator is at 1 V, the regulated output will be 1 V. But if the voltage at the Track pin rises to 3 V, the regulated output will not go higher than 2.5 V.
When under track control, the regulated output from the module follows the voltage at its Track pin on a volt­for-volt basis. By connecting the Track pin of a number of these modules together, the output voltages will fol­low a common signal during power-up and power-down. The control signal can be an externally generated master ramp waveform, or the output voltage from another power supply circuit corporates an internal RC charge circuit. This operates off the module’s input voltage to produce a suitable rising waveform at power up.
Typical Application
The basic implementation of Auto-Track allows for simultaneous voltage sequencing of a number of Auto­Track compliant modules. Connecting the Track control pins of two or more modules forces the Track control of all modules to follow the same collective RC ramp wave­form, and allows them to be controlled through a single transistor or switch; Q1 in Figure 3-5.
To initiate a power-up sequence, it is recommended that the Track control be first pulled to ground potential. This should be done at or before input power is applied to the modules, and then held for at least 10 ms thereaf­ter. This brief period gives the modules time to complete their internal soft-start initialization. Applying a logic­level high signal to the circuit’s On/Off Control turns
on and applies a ground signal to the Track pins. After
Q
1
completing their internal soft-start intialization, the out­put of all modules will remain at zero volts while Q1 is on.
10 ms after a valid input voltage has been applied to the modules, Q trol voltage to automatically rise toward to the modules' input voltage. During this period the output voltage of each module will rise in unison with other modules, to its respective set-point voltage.

Figure 3-6 shows the output voltage waveforms from the circuit of Figure 3-5 after the On/Off Control is set from a high to a low-level voltage. The waveforms, Vo1 and Vo represent the output voltages from the two power mod­ules, U1 (3.3 V) and U2 (2 V) respectively. Vo1 and Vo
2
are shown rising together to produce the desired simul­taneous power-up characteristic.
The same circuit also provides a power-down sequence. Power down is the reverse of power up, and is accom­plished by lowering the track control voltage back to zero volts. The important constraint is that a valid input voltage must be maintained until the power down is complete. It also requires that Q
be turned off relatively slowly. This
1
is so that the Track control voltage does not fall faster than Auto-Track's slew rate capability, which is 1 V/ms. The components R1 and C1 in Figure 3-5 limit the rate at which Q1 can pull down the Track control voltage. The values of 100 k-ohm and 0.1 µF correlate to a decay rate of about 0.17 V/ms.
The power-down sequence is initiated with a low-to-high transition at the On/Off Control input to the circuit. Figure 3-7 shows the power-down waveforms. As the Track control voltage falls below the nominal set-point voltage of each power module, then its output voltage decays with all the other modules under Auto-Track control.
Notes on Use of Auto-Track™
1. The Track pin voltage must be allowed to rise above the module’s set-point voltage before the module can regulate at its adjusted set-point voltage.
2. The Auto-Track function will track almost any voltage ramp during power up, and is compatible with ramp speeds of up to 1 V/ms.
3. The absloute maximum voltage that may be applied to the Track pin is the input voltage V
4. The module will not follow a voltage at its Track control input until it has completed its soft-start initialization. This takes about 10 ms from the time that the module has sensed that a valid voltage has been applied its input. During this period, it is recommended that the Track pin be held at ground potential.
5. The module is capable of both sinking and sourcing current when following a voltage at its Track pin. Therefore startup into an output prebias cannot be supported when a module is under Auto-Track control.
Note: A pre-bias holdoff is not necessary when all supply voltages rise simultaneously under the control of Auto-Track.
6. The Auto-Track function can be disabled by connecting the Track pin to the input voltage (V is disabled, the output voltage will rise at a quicker and more linear rate after input power is applied.

This provides a convenient method for dynamically testing the operation of the load circuit over its supply margin or range. It can also be used to verify the function of supply voltage supervisors. The ±5 % change is applied to the adjusted output voltage, as set by the external resistor, R
at the Vo Adjust pin.

The 5 % adjustment is made by pulling the appropriate margin control input directly to the GND terminal

A low-leakage open-drain device, such as an n-channel MOSFET or p-channel JFET is recommended for this

purpose
. Adjustments of less than 5 % can also be accom­modated by adding series resistors to the control inputs. The value of the resistor can be selected from Table 3-2, or calculated using the following formula.
Up/Down Adjust Resistance Calculation
To reduce the margin adjustment to something less than 5 %, series resistors are required (See RD and RU in Figure 3-8). For the same amount of adjustment, the resistor value calculated for RU and RD will be the same. The formulas is as follows.

Notes:
1. The Margin Up* and Margin Dn* controls were not intended to be activated simultaneously. If they are their affects on the output voltage may not completely cancel, resulting in the possibility of a slightly higher error in the output voltage set point.
2. The ground reference should be a direct connection to the module GND at pin 7 (pin 1 for the PTHxx050). This will produce a more accurate adjustment at the load circuit terminals. The transistors Q

be located close to the regulator.
.
3. The Margin Up and Margin Dn control inputs are not compatible with devices that source voltage. This includes TTL logic. These are analog inputs and should only be controlled with a true open-drain device (preferably a discrete MOSFET transistor). The device selected should have low off-state leakage current. Each input sources 8 µA when grounded, and has an open-circuit voltage of 0.8 V.

Application Notes
PTH Series of Wide-Output Adjust Power Modules (12-V Input)
Remote Sense
The PTH12060W, PTH12010W, PTH12020W, and PTH12030W products incorporate an output voltage sense pin, Vo Sense. The Vo Sense pin should be connected to V
at the load circuit (see data sheet standard appli-
out
cation). A remote sense improves the load regulation performance of the module by allowing it to compensate for any ‘IR’ voltage drop between itself and the load. An IR drop is caused by the high output current flowing through the small amount of pin and trace resistance. Use of the remote sense is optional. If not used, the Vo Sense pin can be left open-circuit. An internal low-
value resistor (15- or less) is connected between the
Vo Sense and V in regulation.
With the sense pin connected, the difference between the voltage measured directly between the V pins, and that measured from Vo Sense to GND, is the amount of IR drop being compensated by the regulator. This should be limited to a maximum of 0.3 V.
Note: The remote sense feature is not designed to compensate for the forward drop of non-linear or frequency dependent components that may be placed in series with the converter output. Examples include OR-ing diodes, filter inductors, ferrite beads, and fuses. When these components are enclosed by the remote sense connection they are effectively placed inside the regulation control loop, which can adversely affect the stability of the regulator.
