Description

The 12V PicoTLynxTM 3A power modules are non-isolated dc-dc converters that can deliver up to 3A of output current. These
modules operate over a wide range of input voltage (V

= 4.5Vdc-14Vdc) and provide a precisely regulated output voltage from

IN

0.59Vdc to 5.5Vdc, programmable via an external resistor. Features include remote On/Off, adjustable output voltage, over
current and overtemperature protection, and output voltage sequencing (APTS versions). The Ruggedized version (-D) is capable
of operation up to 105°C and withstand high levels of shock and vibration. A new feature, the Tunable Loop

TM

, allows the user to
optimize the dynamic response of the converter to match the load with reduced amount of output capacitance leading to
savings on cost and PWB area.

CAUTION: This power module is not internally fused. An input line fuse must always be used.

This power module can be used in a wide variety of applications, ranging from simple standalone operation to an integrated part of
sophisticated power architecture. To preserve maximum flexibility, internal fusing is not included; however, to achieve maximum
safety and system protection, always use an input line fuse. The safety agencies require a fast-acting fuse with a maximum rating
of 5A (see Safety Considerations section). Based on the information provided in this data sheet on inrush energy and maximum dc
input current, the same type of fuse with a lower rating can be used. Refer to the fuse manufacturer’s data sheet for further
information.

Design Considerations

Input Filtering

The 12V PicoTLynxTM 3A module should be connected to a
low ac-impedance source. A highly inductive source can
affect the stability of the module. An input capacitance
must be placed directly adjacent to the input pin of the
module, to minimize input ripple voltage and ensure
module stability.

To minimize input voltage ripple, ceramic capacitors are
recommended at the input of the module. Figure 40
shows the input ripple voltage for various output voltages
at 3A of load current with 1x10 µF or 1x22 µF ceramic
capacitors and an input of 12V.

voltages with 1x10 µF or 1x22 µF ceramic capacitors at
the input (3A load). Input voltage is 12V.

Output Filtering

The 12V PicoTLynxTM 3A modules are designed for low
output ripple voltage and will meet the maximum output
ripple specification with 0.1 µF ceramic and 10 µF ceramic
capacitors at the output of the module. However, additional
output filtering may be required by the system designer for
a number of reasons. First, there may be a need to further
reduce the output ripple and noise of the module. Second,
the dynamic response characteristics may need to be
customized to a particular load step change.

To reduce the output ripple and improve the dynamic
response to a step load change, additional capacitance at
the output can be used. Low ESR polymer and ceramic
capacitors are recommended to improve the dynamic
response of the module. Figure 41 provides output ripple
information for different external capacitance values at
various Vo and a full load current of 3A. For stable operation
of the module, limit the capacitance to less than the
maximum output capacitance as specified in the electrical
specification table. Optimal performance of the module can
be achieved by using the Tunable Loop
later in this data sheet.

Safety Considerations

For safety agency approval the power module must be
installed in compliance with the spacing and separation
requirements of the end-use safety agency standards, i.e., UL
60950-1, CSA C22.2 No. 60950-1-03, and VDE 0850:2001-12
(EN60950-1) Licensed.

For the converter output to be considered meeting the
requirements of safety extra-low voltage (SELV), the input
must meet SELV requirements. The power module has extra­low voltage (ELV) outputs when all inputs are ELV.

The input to these units is to be provided with a fast-acting
fuse with a maximum rating of 5A in the positive input lead

.

Feature Descriptions

Remote On/Off

The 12V PicoTLynxTM 3A modules feature an On/Off pin for
remote On/Off operation. Two On/Off logic options are
available. In the Positive Logic On/Off option, (device code
suffix “4” – see Ordering Information), the module turns ON
during a logic High on the On/Off pin and turns OFF during a
logic Low. With the Negative Logic On/Off option, (no device
code suffix, see Ordering Information), the module turns OFF
during logic High and ON during logic Low. The On/Off
signal is always referenced to ground. For either On/Off logic
option, leaving the On/Off pin disconnected will turn the
module ON when input voltage is present.

For positive logic modules, the circuit configuration for using
the On/Off pin is shown in Figure 42. When the external
transistor Q1 is in the OFF state, the internal PWM Enable
signal is pulled high through an internal 1.5MΩ resistor and
the external pullup resistor and the module is ON. When
transistor Q1 is turned ON, the On/Off pin is pulled low and
the module is OFF. A suggested value for R

For negative logic On/Off modules, the circuit configuration
is shown in Fig. 43. The On/Off pin should be pulled high with
an external pull-up resistor (suggested value for the 4.5V to
14V input range is 20Kohms). When transistor Q2 is in the
OFF state, the On/Off pin is pulled high, transistor Q1 is
turned ON and the module is OFF. To turn the module ON,
Q2 is turned ON pulling the On/Off pin low, turning transistor
Q1 OFF resulting in the PWM Enable pin going high.

Overcurrent Protection

To provide protection in a fault (output overload) condition,
the unit is equipped with internal current-limiting circuitry
and can endure current limiting continuously. At the point of
current-limit inception, the unit enters hiccup mode. The unit
operates normally once the output current is brought back
into its specified range.

Over Temperature Protection

To provide protection in a fault condition, the unit is
equipped with a thermal shutdown circuit. The unit will
shutdown if the overtemperature threshold of 140
exceeded at the thermal reference point T
shutdown is not intended as a guarantee that the unit will
survive temperatures beyond its rating. Once the unit goes
into thermal shutdown it will then wait to cool before
attempting to restart.

Input Undervoltage Lockout

At input voltages below the input undervoltage lockout limit,
the module operation is disabled. The module will begin to
operate at an input voltage above the undervoltage lockout
turn-on threshold.

Output Voltage Programming

The output voltage of the 12V PicoTLynxTM 3A module can
be programmed to any voltage from 0.59dc to 5.5Vdc by
connecting a resistor between the Trim and GND pins of the
module. Certain restrictions apply on the output voltage set
point depending on the input voltage. These are shown in
the Output Voltage vs. Input Voltage Set Point Area plot in
Fig. 44. The Upper Limit curve shows that for output
voltages of 0.9V and lower, the input voltage must be lower
than the maximum of 14V. The Lower Limit curve shows
that for output voltages of 3.8V and higher, the input voltage
needs to be larger than the minimum of 4.5V.

use the following equation:

Remote Sense

The 12V PicoTLynxTM 3A modules have a Remote Sense
feature to minimize the effects of distribution losses by
regulating the voltage at the SENSE pin. The voltage
between the SENSE pin and VOUT pin must not exceed 0.5V.
Note that the output voltage of the module cannot exceed
the specified maximum value. This includes the voltage drop
between the SENSE and Vout pins. When the Remote Sense
feature is not being used, connect the SENSE pin to the
VOUT pin.

4.5Vdc –14Vdc input; 0.59Vdc to 5.5Vdc output; 3A Output Current

Monotonic Start-up and Shutdown

The 12V PicoTLynxTM 3A modules have monotonic start-up
and shutdown behavior for any combination of rated input
voltage, output current and operating temperature range.

Startup into Pre-biased Output

The 12V Pico TLynxTM 3A modules can start into a prebiased
output as long as the prebias voltage is 0.5V less than the
set output voltage. Note that prebias operation is not
supported when output voltage sequencing is used.

Output Voltage Sequencing

The 12V PicoTLynxTM 3A modules (APTS versions) include a
sequencing feature, EZ-SEQUENCE that enables users to
implement various types of output voltage sequencing in
their applications. This is accomplished via an additional
sequencing pin. When not using the sequencing feature,
either tie the SEQ pin to V

When an analog voltage is applied to the SEQ pin, the
output voltage tracks this voltage until the output reaches
the set-point voltage. The final value of the SEQ voltage
must be set higher than the set-point voltage of the module.
The output voltage follows the voltage on the SEQ pin on a
one-to-one volt basis. By connecting multiple modules
together, multiple modules can track their output voltages
to the voltage applied on the SEQ pin.

For proper voltage sequencing, first, input voltage is applied
to the module. The On/Off pin of the module is left
unconnected (or tied to GND for negative logic modules or

IN for positive logic modules) so that the module is

tied to V
ON by default. After applying input voltage to the module, a
minimum 10msec delay is required before applying voltage
on the SEQ pin. During this time, a voltage of 50mV (± 20
mV) is maintained on the SEQ pin. This delay gives the
module enough time to complete its internal power-up soft­start cycle. During the delay time, the SEQ pin should be held
close to ground (nominally 50mV ± 20 mV). This is required
to keep the internal op-amp out of saturation thus
preventing output overshoot during the start of the
sequencing ramp. By selecting resistor R1 (see fig. 47)
according to the following equation

the voltage at the sequencing pin will be 50mV when the
sequencing signal is at zero.

4.5Vdc –14Vdc input; 0.59Vdc to 5.5Vdc output; 3A Output Current

External capacitors are usually added to the output of the
module for two reasons: to reduce output ripple and noise
(see Figure 41) and to reduce output voltage deviations from
the steady-state value in the presence of dynamic load
current changes. Adding external capacitance however
affects the voltage control loop of the module, typically
causing the loop to slow down with sluggish response.
Larger values of external capacitance could also cause the
module to become unstable.

TM

The Tunable Loop

allows the user to externally adjust the
voltage control loop to match the filter network connected
to the output of the module. The Tunable Loop
implemented by connecting a series R-C between the SENSE
and TRIM pins of the module, as shown in Fig. 48. This R-C
allows the user to externally adjust the voltage loop
feedback compensation of the module.

Recommended values of R
capacitor combinations are given in Tables 2 and 3. Table 2
shows the recommended values of R
different values of ceramic output capacitors up to 470uF
that might be needed for an application to meet output
ripple and noise requirements. Selecting R
according to Table 2 will ensure stable operation of the
module.

In applications with tight output voltage limits in the
presence of dynamic current loading, additional output
capacitance will be required. Table 3 lists recommended
values of R
voltage deviation limits for some common output voltages
in the presence of a 1.5A to 3A step change (50% of full
load), with an input voltage of 12V.

After the 10msec delay, an analog voltage is applied to the
SEQ pin and the output voltage of the module will track this
voltage on a one-to-one volt bases until the output reaches
the set-point voltage. To initiate simultaneous shutdown of
the modules, the SEQ pin voltage is lowered in a controlled
manner. The output voltage of the modules tracks the
voltages below their set-point voltages on a one-to-one
basis. A valid input voltage must be maintained until the
tracking and output voltages reach ground potential.

TM

When using the EZ-SEQUENCE

feature to control start-up
of the module, pre-bias immunity during start-up is disabled.
The pre-bias immunity feature of the module relies on the
module being in the diode-mode during start-up. When
using the EZ-SEQUENCE

TM

feature, modules goes through an
internal set-up time of 10msec, and will be in synchronous
rectification mode when the voltage at the SEQ pin is
applied. This will result in the module sinking current if a
pre-bias voltage is present at the output of the module.
When pre-bias immunity during start-up is required, the EZ­SEQUENCE

Power Good

The 12V Pico TLynxTM 3A modules provide a Power Good
(PGOOD) signal that is implemented with an open-drain
output to indicate that the output voltage is within the
regulation limits of the power module. The PGOOD signal will
be de-asserted to a low state if any condition such as
overtemperature, overcurrent or loss of regulation occurs
that would result in the output voltage going ±10% outside
the setpoint value. The PGOOD terminal should be
connected through a pullup resistor (suggested value
100KΩ) to a source of 5VDC or less.

Thermal Considerations

Power modules operate in a variety of thermal environments;
however, sufficient cooling should always be provided to help
ensure reliable operation.

Considerations include ambient temperature, airflow, module
power dissipation, and the need for increased reliability. A
reduction in the operating temperature of the module will
result in an increase in reliability. The thermal data
presented here is based on physical measurements taken in
a wind tunnel. The test set-up is shown in Figure 49. The
preferred airflow direction for the module is in Figure 50.

Shock and Vibration

The ruggedized (-D version) of the modules are designed to withstand elevated levels of shock and vibration to be able to operate in
harsh environments. The ruggedized modules have been successfully tested to the following conditions:

Non operating random vibration:

Random vibration tests conducted at 25C, 10 to 2000Hz, for 30 minutes each level, starting from 30Grms (Z axis) and up to 50Grms
(Z axis). The units were then subjected to two more tests of 50Grms at 30 minutes each for a total of 90 minutes.

Operating shock to 40G per Mil Std. 810F, Method 516.4 Procedure I:

The modules were tested in opposing directions along each of three orthogonal axes, with waveform and amplitude of the shock
impulse characteristics as follows:

All shocks were half sine pulses, 11 milliseconds (ms) in duration in all 3 axes.

Units were tested to the Functional Shock Test of MIL-STD-810, Method 516.4, Procedure I - Figure 516.4-4. A shock magnitude of
40G was utilized. The operational units were subjected to three shocks in each direction along three axes for a total of eighteen
shocks.

Operating vibration per Mil Std 810F, Method 514.5 Procedure I:

The ruggedized (-D version) modules are designed and tested to vibration levels as outlined in MIL-STD-810F, Method 514.5, and
Procedure 1, using the Power Spectral Density (PSD) profiles as shown in Table 1 and Table 2 for all axes. Full compliance with
performance specifications was required during the performance test. No damage was allowed to the module and full compliance
to performance specifications was required when the endurance environment was removed. The module was tested per MIL-STD­810, Method 514.5, Procedure I, for functional (performance) and endurance random vibration using the performance and
endurance levels shown in Table 4 and Table 5 for all axes. The performance test has been split, with one half accomplished before
the endurance test and one half after the endurance test (in each axis). The duration of the performance test was at least 16
minutes total per axis and at least 120 minutes total per axis for the endurance test. The endurance test period was 2 hours
minimum per axis.

Surface Mount Information

Pick and Place

The 12V PicoTLynxTM 3A modules use an open frame
construction and are designed for a fully automated assembly
process. The modules are fitted with a label designed to provide
a large surface area for pick and place operations. The label
meets all the requirements for surface mount processing, as
well as safety standards, and is able to withstand reflow
temperatures of up to 300
information such as product code, serial number and the
location of manufacture.

Nozzle Recommendations

The module weight has been kept to a minimum by using open
frame construction. Variables such as nozzle size, tip style,
vacuum pressure and placement speed should be considered to
optimize this process. The minimum recommended inside
nozzle diameter for reliable operation is 3mm. The maximum
nozzle outer diameter, which will safely fit within the allowable
component spacing, is 7 mm.

Lead Free Soldering

The 12V PicoTLynxTM 3A modules are lead-free (Pb-free) and
RoHS compliant and fully compatible in a Pb-free soldering
process. Failure to observe the instructions below may result in
the failure of or cause damage to the modules and can
adversely affect long-term reliability.

Post Solder Cleaning and Drying Considerations

Post solder cleaning is usually the final circuit-board
assembly process prior to electrical board testing. The
result of inadequate cleaning and drying can affect both
the reliability of a power module and the testability of the
finished circuit-board assembly. For guidance on
appropriate soldering, cleaning and drying procedures,
refer to Board Mounted Power Modules: Soldering and
Cleaning Application Note (AN04-001).

Pb-free Reflow Profile

Power Systems will comply with J-STD-020 Rev. C
(Moisture/Reflow Sensitivity Classification for Nonhermetic Solid
State Surface Mount Devices) for both Pb-free solder profiles
and MSL classification procedures. This standard provides a
recommended forced-air-convection reflow profile based on the
volume and thickness of the package (table 4-2). The suggested
Pb-free solder paste is Sn/Ag/Cu (SAC). The recommended linear
reflow profile using Sn/Ag/Cu solder is shown in Fig. 51.
Soldering outside of the recommended profile requires testing to
verify results and performance.

MSL Rating

The 12V PicoTLynxTM 3A modules have a MSL rating of 2a.

Storage and Handling

The recommended storage environment and handling
procedures for moisture-sensitive surface mount packages is
detailed in J-STD-033 Rev. A (Handling, Packing, Shipping and
Use of Moisture/Reflow Sensitive Surface Mount Devices).
Moisture barrier bags (MBB) with desiccant are required for MSL
ratings of 2 or greater. These sealed packages should not be
broken until time of use. Once the original package is broken,
the floor life of the product at conditions of ≤ 30°C and 60%
relative humidity varies according to the MSL rating (see J-STD­033A). The shelf life for dry packed SMT packages will be a
minimum of 12 months from the bag seal date, when stored at
the following conditions: < 40° C, < 90% relative humidity.
