I have 38vdc, I need between 18 and 25vdc (pretty big difference, I know. I also need -18 to -25vdc). There's a few regulators/buck converters to do that, but I also need 3 amps, that's where things get hard. Knocking it down to 24 and finding a chip that also lets me pull up to 3amps is hard to find. Are there other options to get some amperage headroom after a 1 amp regulator? A current buffer comes to mind, but I've never played with any. And "Current Buffer" just sounds like something I would need lol.
This is all in effort to learn and build some audio circuits, but mostly to not spend money on another transformer that would probably better suite the power supply circuit.
