FDD6670S

FDD6670S September 2001 FDD6670S 30V N-Channel PowerTrench® SyncFET ™ General Description The FDD6670S 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 FDD6670S includes an integrated Schottky diode using Fairchild’s monolithic SyncFET technology. The performance of the FDD6670S as the low-side switch in a synchronous rectifier is indistinguishable from the performance of the FDD6670A in parallel with a Schottky diode. Features 64 A, 30 V RDS(ON) = 9 mΩ @ VGS = 10 V RDS(ON) = 12.5 mΩ @ VGS = 4.5 V Includes SyncFET Schottky body diode Low gate charge (17nC typical) High performance trench technology for extremely low RDS(ON) High power and current handling capability .
