Abstract

A 50MHz to 100MHz dc-dc power converter using Gallium Arsenide power switches is studied. GaAs Schottky rectifiers with high breakdown voltage and very small Ron x Con switching quality factor have been fabricated. A 10V to 5V (or 8V) prototype with an output power of 2.6 Watts and a power efficiency of 77% has been reported.
