IMX70, IMY70 Series Data Sheet
70 to 90 Watt DC-DC Converters
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 Transients Protection
When V i exceeds 154 V, the converter is temporarily disabled.
Furthermore, a built-in suppressor diode provides effective
protection against higher input transients, which may be
generated for example by short-circuits across the input lines.

Reverse Polarity Protection and Fuse
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
