does anyone have a simple circuit for a 2-3v to 5v boost converter?
I'm looking at Fairchild's FAN5333 boost converter, marketed as a constant current serial led driver, but should be easy enough to use as a low power voltage regulator.
I want to power my 5v led spinner from a pair of AAA batteries and I need 250-300ma of current peak, but not continuous. The batteries don't have to last forever, so efficiency isn't a huge concern, just small size.
