FDS6690AS
30V N-Channel PowerTrench® SyncFET™
General Description
The FDS6690AS 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 FDS6690AS includes an integrated
Schottky diode using Fairchild’s monolithic SyncFET technology. The performance of the FDS6690AS as the low-side switch in a synchronous rectifier is close to the performance of the FDS6690A in parallel with a
Schottky diode.
