FDD6688S 30V N-Channel SyncFET

November 2007

FDD6688S
30V N-Channel SyncFET

The FDD6688S is designed to replace a single TO-252 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 FDD6688S includes an integrated Schottky diode using Fairchild’s monolithic SyncFET technology.
• DC/DC converter
• Motor Drives
• 88 A, 30 V.

RDS ON = VGS = 10 V RDS ON = VGS = V
• Low gate charge 31 nC typical
• Fast switching
• High performance trench technology for extremely low RDS ON
