DATASHEET
6A Analog PicoDLynxTM: Non-Isolated DCDC Power Modules
3Vdc - 14.4Vdc input; 0.6Vdc to 5.5Vdc output; 6A Output Current
The 6A Analog PicoDLynxTM power modules
are non-isolated dc-dc converters that can
deliver up to 6A 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.

Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are
absolute stress ratings only, functional operation of the device is not implied at these or any other conditions in
excess of those given in the operations sections of the data sheet. Exposure to absolute maximum ratings for

An input capacitance must be placed

To minimize input voltage ripple, ceramic capacitors

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., ANSI/UL* 62368-1 and CAN/
CSA† C22.2 No. 62368-1 Recognized, DIN VDE‡ 08681/A11:2017 (EN62368-1:2014/A11:2017).
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 10 A, 125Vdc in
the positive input lead.
Feature Descriptions
Figure 40. Circuit configuration for using positive On/Off logic.
For negative logic On/Off modules, the circuit
configuration is shown in Fig. 41.
The On/Off pin should be pulled high with an
external pull-up resistor (suggested value for the 3V
to 14.4V input range is 20Kohms). When transistor Q1
is in the OFF state, the On/Off pin is pulled high,
internal transistor Q4 is turned ON and the module is
OFF. To turn the module ON, Q1 is turned ON pulling

On/Off logic options are available. In the Positive
Logic On/Off option, (device code suffix “4” – see

(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.

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-STD-810, 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.
