Voltage booster from discrete components

Posted on Friday, September 9th, 2011 in components by Ian

This is a simple voltage booster based on discrete components:

The circuit is excellent and works down to 0.6V. It requires about 0.9V to start. I’ve got efficiencies of 80% using high gain transistors.

Thanks Rohit! Via the forum.
