Here is an app note from Microchip that describes how to built a single battery boost converter. It provides a way to power higher voltage circuits with a lower voltage battery.

The design is based around the MCP1640 IC. It is a 350mA 500Khz boost converter with an integrated switch. Due to it’s design the device requires very few external components to function. One Inductor, two capacitors, and two resistors are all that is needed.

The efficiency ranges from 60% to 90% depending on the load and input voltage.
