General Description

This MOSFET is designed to replace a single MOSFET and parallel 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 FDP/B6676S includes an integrated Schottky diode using Fairchild’s monolithic SyncFET technology. The performance of the FDP/B6676S as the low-side switch in a synchronous rectifier is indistinguishable from the performance of the FDP/B6676 in parallel with a Schottky diode.

Features
