[sdiy] Re: most efficient way to get 5V from 12V?

[Danjel van Tijn]

Since the module is only generating gates (no audio) I wonder if I can
get away with using a max5035 chip or some other switching step down
regulator?  Will this generate power rail noise that would affect the
rest of the modular?
