Input Source Impedance
The converter should be connected to a low impedance input source. Highly inductive source impedance can
affect the stability of the converter. An input external L-C filter is recommended to minimize input reflected ripple
current. The inductor has a simulated source impedance of 12μH and the capacitor is Nippon chemi-con KY series
220μF/100V. The capacitor must be located as close as possible to the input terminals of the power module for lowest
impedance.
Output Over Current Protection
When excessive output currents occur in the system, circuit protection is required on all converters. Normally,
overload current is maintained at approximately 150 percent of rated current for PXF40-xxSxx series.
Hiccup-mode is a method of operation in a converter whose purpose is to protect the power supply from being
damaged during an over-current fault condition. It also enables the converter to restart when the fault is removed.
There are other ways of protecting the converter when it is over-loaded, such as the maximum current limiting or
current foldback methods.
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 these devices may exceed their specified limits. A
protection mechanism has to be used to prevent these power devices from being damaged.
The operation of hiccup is as follows. When the current sense circuit sees an over-current event, the controller
shuts off the converter for a given time and then tries to start up the converter again. If the over-load condition has
been removed, the converter will start up and operate normally; otherwise, the controller will see another over-current
event and will shut off the converter again, repeating the previous cycle. Hiccup operation has none of the drawbacks
of the other two protection methods, although its circuit is more complicated because it requires a timing circuit. The
excess heat due to overload lasts for only a short duration in the hiccup cycle, hence the junction temperature of the
power devices is much lower.

30W, Single Output
Output Over Voltage Protection
The output over-voltage protection consists of an output Zener diode that monitors the voltage on the output
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 mode.
During a short circuit condition the converter will shut down. The average current during this condition will be very
low.
Thermal Consideration
The converter operates in a variety of thermal environments. However, 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 the figure below. The temperature at this
location should not exceed 100°C. When operating, adequate cooling must be provided to maintain the test point
temperature at or below 100°C. Although the maximum point temperature of the converter is 100°C, limiting this
temperature to a lower value will yield higher reliability.

Heat Sink Consideration
Use heat-sink (7G-0011C-F) f for lowering temperature and higher reliability of the module.

Remote ON/OFF Control
The Remote ON/OFF Pin is used to turn on and off the DC-DC converter. The user must use a switch to control
the logic voltage (high or low level) of the ON/OFF pin, referenced to -Vi. The switch can be an open collector
transistor, FET or Opto-Coupler that is capable of sinking up to 0.5 mA at low-level logic Voltage. High-level logic of
the ON/OFF signal (maximum voltage): the allowable leakage current of the switch at 12V is 0.5mA.

Output Voltage Adjustment
Output voltage set point adjustment allows the user to increase or decrease the output voltage set point of a
module. This is accomplished by connecting an external resistor between the TRIM pin and either the Vo(+) or Vo(-)
pins. With an external resistor between the TRIM and Vo(-) pin, the output voltage set point increases. With an external
resistor between the TRIM and Vo(+) pin, the output voltage set point decreases.

Safety and Installation Instruction
Fusing Consideration
Caution: This converter is 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 maximum rating of 6A. Based on the information provided in this data sheet on
Inrush 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 PXE30-xxSxx DC/DC converters has been calculated using:
Bellcore TR-NWT-000332 Case I: 50% stress, Operating Temperature at 40°C (Ground fixed and controlled
6
environment ). The resulting figure for MTBF is 1.316×10 hours.
MIL-HDBK-217F NOTICE2 FULL LOAD, Operating Temperature at 25°C ℃. The resulting figure for MTBF is
5
3.465×10 hours.
