People are always asking me if you can really tell that much from a component datasheet (if you’re not an electrical engineer). Greg Lipscomb shows how to figure out what a chip can do by reasoning through a datasheet’s pin-out diagram and schematics. Here he uses the datasheet for the Maxim Max756 DC/DC step-up converter chip found in Ladyada’s Minty Boost portable USB charger.
