... FDS6690AS 30V N-Channel PowerTrench 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 R and low gate charge. The FDS6690AS DS(ON) includes an integrated Schottky diode using Fairchild’s monolithic SyncFET technology ...
