Wide input DC/DC converter 7.5-450VDC 100watt+
Developed for an in house application, these converters can be made for applications from a few watts up to hundreds of watts. Also providing an additional 12V (for example) aux supply for user control electronics.

For some applications  e.g. fuel cells, or special battery inputs, a wide input range is required for a DC/DC converter to provide constant auxilliary output volts at say 5,12, 15 or 24V at power levels up to 100's of watts.

At the low power end a simple flyback may suffice, but even these have limitations.

Our wide input DC/DC converters currently span typically 7.5 to 220VDC, and can in fact operate up to 450VDC if required.

This is an input range of  60:1  (more commonly 20:1 for a typical requirement of 7.5 - 150VDC).

We are developing a wider input range of 3 - 200V (450V max on request) with the possibility of extending the low end to 1.5 and possibly 0.6Vin.

Multiple outputs with coupled inductors can be provided where required.
