General Description

The FDS6990AS is designed to replace a dual SO-8 MOSFET and two Schottky diodes 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.Each MOSFET includes integrated Schottky diodes using Fairchild’s monolithic SyncFET technology. The performance of the FDS6990AS as the low-side switch in a synchronous rectifier is similar to the performance of the FDS6990A in parallel with a Schottky diode.
