The FDD6680AS is designed to replace a single 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 FDD6680AS includes an integrated Schottky diode using a monolithic SyncFET™ technology. The performance of the FDD6680AS as the low-side switch in a synchronous rectifier is indistinguishable from the performance of the FDD6680A in parallel with a Schottky diode.
