Description

The 12V PicoTLynxTM 2A power modules are non-isolated dc-dc converters that can deliver up to 2A of output current. These
modules operate over a wide range of input voltage (V

0.6Vdc to 5.5Vdc, programmable via an external resistor. Features include remote On/Off, adjustable output voltage, over current
and over temperature protection. A new feature, the Tunable Loop
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 4A (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.

The 12V PicoTLynxTM 2A 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 2A of load current with 1x10 µF or 1x22 µF
ceramic capacitors and an input of 5V. Figure 41
shows the input ripple voltage for an input of 12V

Output Filtering

The 12V PicoTLynxTM 2A modules are designed for low
output ripple voltage and will meet the maximum output
ripple specification with 0.1 µF ceramic and 22µF 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.
A minimum 22uF External Cap must be used. Figure 52 provides
output ripple information for different external capacitance
values at various Vo and for a load current of 2A. 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

Feature Descriptions

Remote Enable

The 12V PicoTLynxTM 2A power 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 53.

Safety Considerations

Rpullup

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, and DIN EN 60950-1 (VDE 0805 Teil 1):2006­11

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 extra-low

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.

Overtemperature 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
reference point T
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 2A modules can be
programmed to any voltage from 0.6dc 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. 55. The
Lower Limit curve shows that for output voltages of 2.4V and
higher, the input voltage needs to be larger than the minimum
of 3V.

Without an external resistor between Trim and GND pins, the
output of the module will be 0.6Vdc. To calculate the value of
the trim resistor, Rtrim for a desired output voltage, use the
following equation:

Rtrim is the external resistor in kΩ

Remote Sense

The 12V PicoTLynxTM 2A power 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.

less than the set output voltage.

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
±12.5% outside the setpoint value. The PGOOD terminal
should be connected through a pullup resistor
(suggested value 100KΩ) to a source of 5VDC or lower.

The 12V PicoTLynxTM 2A modules have a new feature

.

External capacitors are usually added to the output of
the module for two reasons: to reduce output ripple and
noise (see Fig. 52) 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

TM

is implemented by connecting a series R-C

Loop
between the SENSE and TRIM pins of the module, as
shown in Fig. 11. This R-C allows the user to externally
adjust the voltage loop feedback compensation of the
module.

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 59. The preferred airflow direction
for the module is in Figure 60.

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 6 and Table 7 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 6 and Table 7 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 2A 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.

Bottom Side / First Side Assembly

This module is not recommended for assembly on the bottom
side of a customer board. If such an assembly is attempted,
components may fall off the module during the second reflow
process. If assembly on the bottom side is planned, please
contact GE Critical Power for special manufacturing process
instructions.

Only ruggedized (-D version) modules with additional epoxy will
work with a customer’s first side assembly. For other versions,
first side assembly should be avoided

Lead Free Soldering

The 12V PicoTLynxTM 2A 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.

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-air­convection reflow profile based on the volume and
thickness of the package (table 4-2). The suggested Pb­free solder paste is Sn/Ag/Cu (SAC).

MSL Rating

The 12V PicoTLynxTM 2A 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-STD-033A). 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.

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).
