FDP6644S/FDB6644S
30V N-Channel PowerTrench SyncFET™
General Description
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 FDP6644S includes
an integrated Schottky diode using Fairchild’s
monolithic SyncFET technology. The performance of
the FDP6644S/FDB6644S as the low-side switch in a
synchronous rectifier is indistinguishable from the
performance of the FDP6644/FDB6644 in parallel with
a Schottky diode.
Features
• 28 A, 30 V.
RDS(ON) = 10 mΩ @ VGS = 10 V
RDS(ON) = 12 mΩ @ VGS = 4.5 V
• Includes SyncFET Schottky body diode
• Low gate charge (27nC typical)
• High performance trench technology for extremely
low RDS(ON) and fast switching
• High power and current handling capability
