PMP20850: Modifying the output voltage from 3.3V to 12V

Yen Ting Chu

Part Number: PMP20850

HI Team,

My customer would design an application transforming from -48V to 12V, with isolation protection and it seems PMP20850 also fits the spec. How to modify the design such that it can output 12V? Thanks.

Best regards,

Andy Chu

HI Andy,

The more important specification is the output power level, what does your customer need?

Once that is determined, if it is the same as PMP20850 then you might only have to change the transformer turns ratio.

I am also going to loop in the original designer.

Thanks,

Robert

Hi Andy,

There might be another design that is closer to your requirements. I suggest using the TI reference designs quick search tool to find one that matches your requirements. Here is a link to the search tool.
