DESCRIPTION

The PTH05T210W is a high-performance 30-A rated, non-isolated power module which utilizes a multi-phase,
switch-mode topology. This module represents the 2nd generation of the PTH series power modules which
includes a reduced footprint and improved features.

Operating from an input voltage range of 4.5 V to 5.5 V, the PTH05T210W requires a single resistor to set the
output voltage to any value over the range, 0.7 V to 3.6 V. The module uses double-sided surface mount
construction to provide a low profile and compact footprint. Package options include both through-hole and
surface mount configurations that are lead (Pb) – free and RoHS compatible.

A new feature included in this 2nd generation of PTH modules is TurboTrans™ technology (patent pending).
TurboTrans allows the transient response of the regulator to be optimized externally, resulting in a reduction of
output voltage deviation following a load transient and a reduction in required output capacitance. This feature
also offers enhanced stability when used with ultra-low ESR output capacitors.

The PTH05T210W incorporates a comprehensive list of standard features. They include on/off inhibit, a
differential remote output voltage sense which ensures tight load regulation, and an output overcurrent and
overtemperature shutdown to protect against load faults. A programmable undervoltage lockout allows the
turn-on voltage threshold to be customized. AutoTrack™ sequencing is a feature which simplifies the
simultaneous power-up and power-down of multiple modules in a power system by allowing the outputs to track
a common voltage.

Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

DESCRIPTION

2, 6 The positive input voltage power node to the module, which is referenced to common GND.

5, 9 The regulated positive power output with respect to the GND.

3, 4 This is the common ground connection for the VIand VOpower connections. It is also the 0 Vdcreference for the
7, 8 control inputs.

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 open-circuit, the
module produces an output whenever a valid input source is applied. This input is not compatible with TTL logic

1

devices and should not be tied to VIor any other voltage.

This pin is also used for input undervoltage lockout (UVLO) programming. Connecting a resistor from this pin to
GND (pin 3) allows the ON threshold of the UVLO to be adjusted higher than the default value. For more
information, see the Application Information section.

A 0.1 W 1% resistor must be directly connected between this pin and pin 8 (GND) to set the output voltage to a
value higher than 0.7 V. The temperature stability of the resistor should be 100 ppm/°C (or better). The setpoint

value. For further information, on output voltage adjustment see the related application note. The specification
table gives the preferred resistor values for a number of standard output voltages.

The sense input allows the regulation circuit to compensate for voltage drop between the module and the load.
For optimal voltage accuracy, +Sense must be connected to VO, very close to the load.

The sense input allows the regulation circuit to compensate for voltage drop between the module and the load.
For optimal voltage accuracy, –Sense must be connected to GND (pin 8), very close to the load.

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 module's output voltage follows 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, this input should be connected to VI.

NOTE: Due to the undervoltage lockout feature, the output of the module cannot follow its own input voltage
during power up. For more information, see the related application note.

This input pin adjusts the transient response of the regulator. To activate the TurboTrans™ feature, a 1%, 50
mW resistor must be connected between this pin and pin 10 (+Sense) very close to the module. For a given
value of output capacitance, a reduction in peak output voltage deviation is achieved by using this feature. If
unused, this pin must be left open-circuit. External capacitance must never be connected to this pin. The
resistance requirement can be selected from the TurboTrans™ resistor table in the Application Information
section.

APPLICATION INFORMATION

CAPACITOR RECOMMENDATIONS FOR THE PTH05T210W POWER MODULE

Input Capacitor (Required)

The size and value of the input capacitor is determined by the converter’s transient performance capability. The
minimum amount of required input capacitance is 1000 µF, with an RMS ripple current rating of 1000 mA. This
minimum value assumes that the converter is supplied with a responsive, low inductance input source. This
source should have ample capacitive decoupling, and be distributed to the converter via PCB power and ground
planes.

For high-performance/transient applications, or wherever the input source performance is degraded, 2000 µF of
input capacitance is recommended. The additional input capacitance above the minimum level insures an
optimized performance.

Ripple current (rms) rating, less than 100 mΩ of equivalent series resistance (ESR), and temperature are the
main considerations when selecting input capacitors. The ripple current reflected from the input of the
PTH05T210W module is moderate to low. Therefore any good quality, computer-grade electrolytic capacitor has
an adequate ripple current rating.

Regular tantalum capacitors are not recommended for the input bus. These capacitors require a recommended
minimum voltage rating of 2 × (maximum dc voltage + ac ripple). This is standard practice to ensure reliability. No
tantalum capacitors were found with a sufficient voltage rating to meet this requirement. When the operating
temperature is below 0°C, the ESR of aluminum electrolytic capacitors increases. For these applications,
Os-Con, poly-aluminum, and polymer-tantalum types should be considered. Adding one or two ceramic
capacitors to the input attenuates high-frequency reflected ripple current.

TurboTrans Output Capacitor

The PTH05T210W requires a minimum output capacitance of 470 µF. The required capacitance above 470µFis
determined by actual transient deviation requirements.

TurboTrans allows the designer to optimize the capacitance load according to the system transient design
requirement. High quality, ultra-low ESR capacitors are required to maximize TurboTrans effectiveness.
Capacitors with a capacitance (µF) × ESR (mΩ) product of ≤ 10,000 mΩ×µF are required.

Working Example:

A bank of 6 identical capacitors, each with a capacitance of 680 µF and 5 mΩ ESR, has a C × ESR product of
3400 µFxmΩ (680 µF × 5 mΩ).

Using TurboTrans in conjunction with the high quality capacitors (capacitance (µF) × ESR (mΩ)) reduces the
overall capacitance requirement while meeting the minimum transient amplitude level.

Table 1 includes a preferred list of capacitors by type and vendor. See the Output Bus / TurboTrans column.

Note: See the TurboTrans Technology Application Notes within this document for selection of specific
capacitance.

Non-TurboTrans Output Capacitor

The PTH05T210W requires a minimum output capacitance of 470 µF. Non-TurboTrans applications must
observe minimum output capacitance ESR limits.

A combination of 200 µF of ceramic capacitors plus low ESR (15 mΩ to 30 mΩ) Os-Con electrolytic/tantalum
type capacitors can be used. When using Polymer tantalum types, tantalum type, or Oscon types only, the
capacitor ESR bank limit is 3 mΩ to 5 mΩ. (Note: no ceramic capacitors are required). This is necessary for the
stable operation of the regulator. Additional capacitance can be added to improve the module's performance to
load transients. High quality computer-grade electrolytic capacitors are recommended. Aluminum electrolytic
capacitors provide adequate decoupling over the frequency range, 2 kHz to 150 kHz, and are suitable when
ambient temperatures are above -20°C. For operation below -20°C, tantalum, ceramic, or Os-Con type
capacitors are necessary.

PTH05T210W

SLTS263B–NOVEMBER 2005 – REVISED FEBRUARY 2006

APPLICATION INFORMATION (continued)

When using a combination of one or more non-ceramic capacitors, the calculated equivalent ESR should be no
lower than 2 mΩ (4 mΩ when calculating using the manufacturer’s maximum ESR values). A list of preferred
low-ESR type capacitors, are identified in Table 1.

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 capacitors, with
values between 10 µF and 100 µF, does not exceed 5000 µF (non-TurboTrans). In TurboTrans applications,
when ceramic capacitors are used on the output bus, total capacitance including bulk and ceramic types is not to
exceed 12,000 µF.

Tantalum, Polymer-Tantalum Capacitors

Tantalum type capacitors are only used on the output bus, and are recommended for applications where the
ambient operating temperature is less than 0°C. The AVX TPS series and Kemet capacitor series are suggested
over many other tantalum types due to their higher rated surge, power dissipation, and ripple current capability.
As a caution, many general-purpose tantalum capacitors have higher ESR, reduced power dissipation, and lower
ripple current capability. These capacitors are also less reliable due to their reduced power dissipation and surge
current ratings. Tantalum capacitors that have no stated ESR or surge current rating are not recommended for
power applications.

Capacitor Table

Table 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 ensure both optimum regulator performance and long capacitor life.

Designing for Fast Load Transients

The transient response of the dc/dc converter has been characterized using a load transient with a di/dt of

2.5 A/µs. The typical voltage deviation for this load transient is given in the Electrical Characteristics table using
the minimum required 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 low ESR ceramic capacitor decoupling. Generally, with 50% load steps at > 100 A/µs, adding multiple
10 µF ceramic capacitors, 3225 case size, plus 10 × 1 µF, including numerous high frequency ceramics
(≤ 0.1 µF) are all that is required to soften the transient higher frequency edges. Special attention is essential
with regards to location, types, and position of higher frequency ceramic and lower ESR bulk capacitors. DSP,
FPGA and ASIC vendors identify types, location and capacitance required for optimum performance of the high
frequency devices. The details regarding the PCB layout and capacitor/component placement are important at
these high frequencies. Low impedance buses and unbroken PCB copper planes with components located as
close to the high frequency processor are essential for optimizing transient performance. In many instances
additional capacitors may be required to insure and minimize transient aberrations.

(3) Total bulk nonceramic capacitors on the output bus with ESR of ≥ 15mΩ to ≤ 30mΩ requires an additional ≥ 200 µF of ceramic

capacitor.
(4) Aluminum Electrolytic capacitor not recommended for the TurboTrans due to higher ESR × capacitance products. Aluminum and higher

ESR capacitors can be used in conjunction with lower ESR capacitance.
(5) Output bulk capacitor's maximum ESR is ≥ 30 mΩ. Additional ceramic capacitance of ≥ 200 µF is required.
(6) The minimum capactiance on the input bus can be less than 1000 µF when using this type of capacitor. Insure that the minimum rms

ripple current rating is met.
(7) N/R – Not recommended. The voltage rating does not meet the minimum operating limits.
(8) The voltage rating of this capacitor only allows it to be used for output voltage that is equal to or less than 80% of the working voltage.
