Inrush Current
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.

Input Transient Voltage Protection
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.

Converter start-up and rise time (see table 2)
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.
