Tiny Synchronous Buck Converter in TO-220 Size Reference Design

PMP8581

Design files

Overview

This design is a tiny synchronous buck converter which can be used either for 3.3V or 5.0V output voltage and a maximum current of 600mA. It has the same size like a TO-220 package and can directly replace linear regulators like the well-known uA7805.
