App note: Single battery boost converter
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 […]
