Hi - I end up making a lot of simple power supplies for my PCBs. Most
everything has been DC to DC - lots of linear regs, a couple dc-dc
step downs, even one step up. But I normally just choose a part and go
by what its datasheet says. Are there any good resources for what
sorts of considerations should go into choosing parts to give a clean,
stable, accurate power supply for a PCB? I'm talking about low
voltage, low current stuff. Normally I have a somewhat noisy 12V
signal coming into a PCB and I'll need 3.3V or 5V at a couple hundred
ma from it - so supplies for that sort of situation are what I'm most
interested in.
Any books/websites/app notes/etc.?
Thanks!
