35 Watt Quad-Output DC-DC Converters

Inrush Current

Input Transient Voltage Protection

The inrush current has been kept as low as possible by

choosing a very small input capacitance. A series resistor may

be installed in the input line in order to further reduce this

current.

A built-in suppressor diode provides effective protection

against input transients, which may be generated for example

by short-circuits across the input lines, where the network

inductance may cause high energy pulses.

For very high energy transients as for example to achieve

IEC/EN 61000-4-5 compliance (as per table Electromagnetic

Immunity) an external inductor and capacitor are required. The

components should have similar characteristics as listed in

table below.

Reverse Polarity Protection

The built-in suppressor diode also provides for reverse

polarity protection at the input by conducting current in the

reverse direction. An external fuse is required to limit this

current.
