General Description

The FDS6699S is designed to replace a single SO-8 MOSFET and Schottky diode in synchronous DC:DC power supplies. This 30V MOSFET is designed to maximize power conversion efficiency, providing a low RDS(ON) and low gate charge. The FDS6699S includes an integrated Schottky diode using Fairchild’s monolithic SyncFET technology.
