Input Transient Voltage Protection
In many applications transient voltages on the converter input
are always possible. These may be caused for example by
short circuits between Vi+ and Vi–, where the network
inductance may generate high energy pulses.
In order to protect the converter, a transient voltage
4 Watt DC-DC Converters
Fuse and Reverse Polarity Protection
The suppressor diode on the input also protects against
reverse polarity input voltage. An external fast fuse is required
to limit this reverse current; see table below.
Table 6: External input fuse
suppressor diode is fitted to the input; see table below.

If transients generating currents above the peak pulse current
I PP are possible, an external limiting network such as the circuit
shown in figure 8 is recommended. It provides compliance with
transients according to IEC/EN 61000-4-5, level 2. The comp-
onents are specified in table 5.
If 40IMX4 converters should withstand 150 V transients
according to 19Pfl1, the same external circuitry with similar
components as shown in figure 8 can be used.
