FDP6670AS/FDB6670AS
tm
30V N-Channel PowerTrench® SyncFET™
General Description
Features
This MOSFET is designed to replace a single MOSFET
and parallel 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 FDP6670AS
includes an integrated Schottky diode using Fairchild’s
monolithic SyncFET technology. The performance of
the FDP6670AS/FDB6670AS as the low-side switch in
a synchronous rectifier is indistinguishable from the
performance of the FDP6670A/FDB6670A in parallel
with a Schottky diode.
• 31 A, 30 V.
RDS(ON) = 8.5 mΩ @ VGS = 10 V
RDS(ON) = 10.5 mΩ @ VGS = 4.5 V
• Includes SyncFET Schottky body diode
• Low gate charge (28nC typical)
• High performance trench technology for extremely
low RDS(ON) and fast switching
• High power and current handling capability
