ok smps voodoo doctors and gurus, I need some opinions
my goal is to build an smps that can supply 5v at 2a, ultra-low ripple is not a major concern, the primary goal will be to provide charging current for digital devices with on board charging circuitry.
the source of power for the converter is two or three 2.6 ah lithium cells (rated for high current charge and discharge), ideally in parallel for easier recharging, which means a step-up converter
i don't mind smt, I prefer it actually, but insanely small packages like micro-sop and micro-max are too small for my fabrication abilities, so something in an so, tso or sot package is ideal. looking more for a integrated converter instead of just a controller, but maybe a controller is the only option.
National has a couple of chips that come close, but don't quite fit.
please share your suggestions
