The FDD6680S 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 FDD6680S includes an integrated Schottky diode using Fairchild's monolithic SyncFET technology. The performance of the FDD6680S as the low-side switch in a synchronous rectifier is indistinguishable from the performance of the FDD6680A in parallel with a Schottky diode.
• 55 A, 30 VRDS(ON) = 11 mΩ @ VGS = 10 VRDS(ON) = 17 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
FDD6680S Typical Application
• DC/DC converter • Motor Drives
