Post by thread:[EE]: Boost regulators?

Hi again. Long time no post, although I've been occasionally reading things via the archives... Was there ever any success in the boost switching regulator design? Roman's two-transistor buck converter is lovely, but I'd also like to be able to get 5V from a 3V (or even 1.5V) battery... (TI has an app note for their MSP430 that provides ~2.4V from a single cell using transistor astable oscillator, push-pull driver, and capacitive voltage multiplier, but it's very oriented to the tiny current requirements of MSP320/LCD systems...)
