IMX70, IMY70 Series Data Sheet  
70 to 90 Watt DC-DC Converters  
Inrush Current  
Input Transients 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.  
When Vi 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.

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 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  
current.
