The FDS6690AS 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 FDS6690AS includes an integrated Schottky diode using onsemi’s monolithic SyncFET technology. The performance of the FDS6690AS as the low-side switch in a synchronous rectifier is close to the performance of the FDS6690A in parallel with a Schottky diode.
