Description
The 3A Analog PicoDLynxTM 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 (VIN = 3Vdc-14.4Vdc) and provide a precisely regulated output voltage from
0.6Vdc to 5.5Vdc, programmable via an external resistor. Features include remote On/Off, adjustable output voltage, over
current and over temperature protection. The Tunable LoopTM feature 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.

The 3A Analog PicoDLynxTM 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 37 shows
the input ripple voltage for various output voltages at 3A of
load current with 1x22µF or 2x22µF ceramic capacitors and
an input of 12V.

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 2nd, CSA C22.2 No. 60950-1-07, DIN EN
60950-1:2006 + A11 (VDE0805 Teil 1 + A11):2009-11; EN
60950-1:2006 + A11:2009-03.
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 voltage (ELV) outputs when all inputs are ELV.
The input to these units is to be provided with a fastacting fuse with a maximum rating of 5A, 125VDC in the
positive input lead.
Output Filtering
These 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 38 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 LoopTM feature described later in this data sheet.

3A Analog PicoDLynxTM: Non-Isolated DC-DC Power Modules
3Vdc –14.4Vdc input; 0.6Vdc to 5.5Vdc output; 3A Output Current
Feature Descriptions
Remote On/Off
Monotonic Start-up and Shutdown
The 3A Analog PicoDLynxTM 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 should be
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.
The module has monotonic start-up and shutdown
behavior for any combination of rated input voltage,
output current and operating temperature range.
For positive logic modules, the circuit configuration for using the
On/Off pin is shown in Figure 39. When the external transistor Q2
is in the OFF state, Q3 is ON, Q4 is OFF and the internal PWM
Enable signal is pulled high and the module is ON. When
transistor Q2 is turned ON, Q3 is OFF, Q4 turns ON pulling the
ENABLE pin low and the module is OFF. A suggested value for
Rpullup is 20k.
The output voltage of the module is programmable 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. 41. The Upper Limit curve shows that for output
voltages lower than 1V, the input voltage must be lower
than the maximum of 12V. The Lower Limit curve shows
that for output voltages higher than 0.6V, the input
voltage needs to be larger than the minimum of 3V.

and the module is OFF. To turn the module ON, Q1 is turned ON
pulling the On/Off pin low, turning transistor Q4 OFF resulting in

3A Analog PicoDLynxTM: Non-Isolated DC-DC Power Modules
3Vdc –14.4Vdc input; 0.6Vdc to 5.5Vdc output; 3A Output Current
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, should be
as per the following equation:
12
Rtrim =
k
(Vo − 0.6)
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.
Rtrim is the external resistor in kΩ

Remote Sense
The power module has 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 should not exceed 0.5V.
Voltage Margining
Output voltage margining can be implemented in the module
by connecting a resistor, Rmargin-up, from the Trim pin to the
ground pin for margining-up the output voltage and by
connecting a resistor, Rmargin-down, from the Trim pin to output
pin for margining-down. Figure 43 shows the circuit
configuration for output voltage margining. The POL
Programming Tool, available at www.lineagepower.com under
the Downloads section, also calculates the values of Rmargin-up
and Rmargin-down for a specific output voltage and % margin.
Please consult your local GE technical representative for
additional details.

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 135oC (typ)
is exceeded at the thermal reference point Tref . 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.
Power Good
The module provides 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 can be connected through a
pullup resistor (suggested value 100K) to a source of
5VDC or lower.
Dual Layout
Identical dimensions and pin layout of Analog and Digital
PicoDLynx modules permit migration from one to the
other without needing to change the layout. To support
this, 2 separate Trim Resistor locations have to be
provided in the layout. For the digital modules, the resistor
is connected between the TRIM pad and SGND and in the
case of the analog module it is connected between TRIM
and GND

PicoDLynx on the same pad.
Tunable LoopTM
The 3A PicoDLynxTM modules have a feature that
optimizes transient response of the module called
Tunable LoopTM.
External capacitors are usually added to the output of
the module for two reasons: to reduce output ripple and
noise (see Figure 38) 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.
The Tunable LoopTM allows the user to externally adjust
the voltage control loop to match the filter network
connected to the output of the module. The Tunable
LoopTM is implemented by connecting a series R-C
between the SENSE and TRIM pins of the module, as
shown in Fig. 45. This R-C allows the user to externally
adjust the voltage loop feedback compensation of the
module.

Recommended values of RTUNE and CTUNE for different
output capacitor combinations are given in Tables 2 and
3. Table 2 shows the recommended values of RTUNE and
CTUNE for different values of ceramic output capacitors up
to 1000uF that might be needed for an application to
meet output ripple and noise requirements. Selecting
RTUNE and CTUNE 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 RTUNE and CTUNE in order to meet 2% output
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.
Please contact your GE technical representative to obtain
more details of this feature as well as for guidelines on
how to select the right value of external R-C to tune the

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 46. The preferred airflow direction
for the module is in Figure 47.

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. 810G, 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 810G, Method 514.5 Procedure I:
The ruggedized (-D version) modules are designed and tested to vibration levels as outlined in MIL-STD-810G, 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 12VAnalog PicoDLynxTM 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 300oC. The label also
carries product 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
Only the -D version of this module can be placed at the
bottom side of the customer board. No additional glue or
adhesive is required is required to hold the module during the
top side reflow process
thermocouple should be attached to this test pad since this
will be the coolest solder joints. The temperature of this point
should be:
Maximum peak temperature is 260 C.
Minimum temperature is 235 C.
Dwell time above 217 C: 60 seconds minimum Dwell time
above 235 C: 5 to 15 second
MSL Rating
The 12VAnalog PicoDLynxTM 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. B (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.
Lead Free Soldering
The 12VAnalog PicoDLynxTM 3A modules are lead-free (Pbfree) and RoHS compliant and
are both forward and backward compatible in a Pb-free and
a SnPb 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-air-convection reflow profile
based on the volume and thickness of the package (table 52). The suggested Pb-free solder paste is Sn/Ag/Cu (SAC). For
questions regarding LGA, solder volume; please contact GE
for special manufacturing process instructions.
The recommended linear reflow profile using Sn/Ag/Cu solder
is shown in Fig. 48. Soldering outside of the recommended
profile requires testing to verify results and performance.
It is recommended that the pad layout include a test pad
where the output pin is in the ground plane. The

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).
