High efficiency battery boost regulator using the MCP1640
Giorgos over at PCBheaven made a MCP1640 boost converter for his camping LED light project. It’s designed to squeeze every last bit of energy from the batteries.

What i want now, is something to spice up this hack. So here is what – I used the MCP1640 boost converter to drain the last electron from the batteries. This chip can work with a ridiculous low voltage and provide enough power to drive a couple LEDs. Which means the 2 AA batteries will operate even longer and the LEDs will be much brighter.
