I need a power supply for my dsp application which I imagine will draw at most 500mA(although probably 1/5 that on avg). In any case I was looking for some way to power it. I need both 5V and 3.3V and if possible I'd like to have the option to supply it with a battery with minimal loss(probably a 9V) but otherwise probably something like 9-12V from a wallwart.
Any ics that can do this?
Thanks, Jon
