General Description
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.

FEATUREs
• 55 A, 30 V RDS(ON) = 11 mΩ @ VGS = 10 V RDS(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

APPLICATIONs
• DC/DC converter
• Motor Drives
