November 2007

FDS6689S
30V N-Channel SyncFET

The FDS6689S is designed to replace a single SO-8 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 FDS6688S includes an integrated Schottky diode using Fairchild’s monolithic SyncFET technology.
• Synchronous Rectifier for DC/DC converter
• Notebook Vcore low side switch
• Point of Load low side switch
• 16 A, 30 V.

RDS ON = VGS = 10 V RDS ON = VGS = V
• Includes SyncFET Schottky body diode
• High performance trench technology for extremely low RDS ON and fast switching
• High power and current handling capability
• 100% RG Gate Resistance tested
