18-60 VDC input DC/DC

Posted by: dhandzic on
Is it possible to use a DPA for a wide input (18-60VDC) dc/dc converter if over voltage protection is turned off using a zener?

Hi,

Yes it is possible to design a wide range power supply by disabling the OV protection feature by using a suitable external circuit such as the one suggested by you.

You will need to ensure that the transformer design is carefully done to ensure that the maximum drain-source voltage rating of the DPA switch is not exceeded.
