App Note: Boost converter that works with voltages down to 0.5v
EDN Network covers the design of a very low voltage boost converter. The circuit in question is an LED flashlight designed to power 2 LEDs from voltages as low as 0.5V. The circuit uses an integrated constant current boost converter LT192, though for a cheaper design look no further than the Joule Thief.
