PMP20850: Modifying the output voltage from 3.3V to 12V/3a

Hi Ryan,

The main changes would have to be to the transformer and output inductor.

You would also need to take care with the self driven sync rectifiers to clamp the gate voltage.

Please look at a design like PMP21103.

Thanks, Robert

Ryan,

This is not a simple change, it is very complicated and essentially a completely new design.

Please refer to my other message.

Thanks,

Robert
