FDP6690S/FDB6690S
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 FDP6690S includes an integrated
Schottky diode using Fairchild’s monolithic SyncFET technology. The performance of the FDP6690S/FDB6690S as the low-side switch in a synchronous rectifier is indistinguishable from the performance of the FDP6035AL/FDB6035AL in parallel with a
Schottky diode.
Features
21 A, 30 V. RDS(ON) = 15.5 mΩ @ VGS = 10 V RDS(ON) = 23.0 mΩ @ VGS = 4.5 V Includes SyncFET
Schottky body diode Low gate charge (11nC typical) High performance trench technology for extremely low RDS(ON) and fast switching High power and current handling capability
