FDS6689S
30V N-Channel PowerTrench^® SyncFET^™
General Description
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
R_DS(ON) and low gate charge. The FDS6688S includes
an integrated Schottky diode using Fairchild’s
monolithic SyncFET technology.
Applications
• Synchronous Rectifier for DC/DC converter –
• Notebook Vcore low side switch
• Point of Load low side switch
Features
• 16 A, 30 V.
R_DS(ON) = 5.4 mΩ @ V_GS = 10 V
R_DS(ON) = 6.5 mΩ @ V_GS = 4.5 V
• Includes SyncFET Schottky body diode
• High performance trench technology for extremely low
R_DS(ON) and fast switching
• High power and current handling capability
• 100% R_G (Gate Resistance) tested
