The FDS7066ASN3 is designed to replace a single SO8 FLMP 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 FDS7066ASN3 includes an integrated Schottky diode using Fairchild's monolithic SyncFET technology. The performance of the FDS7066ASN3 as the low-side switch in a synchronous rectifier is close to the performance of the FDS7066N3 in parallel with a Schottky diode.
