FDS6690S
30V N-Channel PowerTrench^® SyncFET^™
General Description
The FDS6690S 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 FDS6690S includes
an integrated Schottky diode using Fairchild’s
monolithic SyncFET technology. The performance of
the FDS6690S as the low-side switch in a synchronous
rectifier is close to the performance of the FDS6690A in
parallel with a Schottky diode.
Applications
• DC/DC converter
• Motor drives
Features
• 10 A, 30 V.
RDS(ON) = 0.016 Ω @ V GS = 10 V
RDS(ON) = 0.024 Ω @ V GS = 4.5 V
• Includes SyncFET Schottky diode
• Low gate charge (11 nC typical)
• High performance trench technology for extremely low
RDS(ON)
• High power and current handling capability
