Input Source Impedance
The converter should be connected to a lowimpedance input source. Highly inductive source impedance can
affectthe stability of the converter. Input external L-C filter is recommended to minimize inputreflected ripple current.
The inductorhas a simulated source impedance of 12μH and capacitor is Nippon chemi-con KY series 47μF/100V.
The capacitor must be located as close as possible to the input terminals of the converter forlower impedance.
Output Over Current Protection
When excessive output currents occur in the system, circuit protection is required on all convert
ers. Normally,
overload current is maintained at approximately 150 percent of rated current for PXD30-xxWDxx series.
Hiccup-
mode is a method of operation in the converter whose purpose is to protect the converter from being
damaged during an over-current fault condition. It also enables the converter to restart when the fault is removed.
One of the problems resulting from over current is that excessive heat may be generated in power devices;
especially MOSFET and Schottky diodes and the temperature of thos
e devices may exceed their specified limits. A
protection mechanism has to be used to prevent those power devices from being damaged.
Output Over Voltage Protection
The output over-voltage protectionconsists of an output Zener diode that monitors the voltage on theoutput
terminals. If the voltage on the output terminals exceeds the over-voltage protection threshold, then the Zener diode
clamps the output voltage.
Short Circuit Protection
Continuous, hiccup and auto-recovery.

The converter operates in a variety of thermal environments. Sufficient cooling should be provided to help ensure
reliable operation of the unit. Heat is removed by conduction, convection, and radiation to the surrounding
environment. Proper cooling can be verified by measuring the point as shown in the figure below. The temperature at
this location should notexceed 105°C. When operating, adequate cooling must be provided to maintain the test point
temperature at or below 105°C .Although the maximum point temperature of the converteris 105°C, limiting this
temperature to a lower value will increase the reliability of this device.
TOPVIEW
Heat Sink Consideration
Use heat-sink (7G-0020C) for lowering temperature; thus increasing the reliability of the converter.

Remote ON/OFF Control
Positive Logic – (no suffix) , the positive logic remote ON/OFF control circuit is included. Ex.: PXD30-24WD05
Turns the converter ON during logic High on the On/Off pin and turns the converter OFF during logic Low.
The On/Off pin is an open collector/drain logic input signal (Von/off) that is referenced to GND.
If not using the remote on/off feature, an open circuit between on/off pin and (–) input pin is needed to
turn the module
on.
Negative Logic – (suffix -N), the negative logic remote ON/OFF control circuit is included. Ex.: PXD30-24WD05-N
Turns the converter ON during logic Low on the On/Off pin and turns the converter OFF during logic High.
The On/Off pin is an open collector/drain logic input signal (Von/off) that is referenced to GND.
If not using the remote on/off feature, a short circuit between on/off pin and (–) input pin is needed to turn the module
on.

Safety and Installation Instructions
Fusing Consideration
Caution:This converteris not internally fused.An input line fuse must always be used.
This encapsulated converter can be used in a wide variety of applications, ranging from simple stand-
alone
operation to an integrated part of a sophisticated power architecture. For
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 slow-blow fuse with a maximum rating of 10A. Based on the information provided in this
data sheet
on i
nrush energy and maximum dc input current; the same type of fuse with lower rating can be used. Refer to the
fuse manufacturer’s data for further information.
MTBF and Reliability
The MTBF of PXD30-xxWDxx series of DC/DC converters has been calculated using:
Bellcore TR-NWT-000332 Case I: 50% stress, Operating Temperature at 40°C ℃(Ground fixed and controlled
environment). The resulting figure for MTBFis 3.163×106hours.
MIL-HDBK 217F NOTICE2 FULL LOAD, Operating Temperature at 25°C ℃. Theresulting figure for MTBF is
4.347×105hours.
