The FDD6680AS is a 30V N-Channel PowerTrench® SyncFET™ designed to replace a single MOSFET and Schottky diode in synchronous DC:DC power supplies. It offers low RDS(ON) and low gate charge to maximize power conversion efficiency. The FDD6680AS features Fairchild's monolithic SyncFET technology, which includes an integrated Schottky diode. The performance of the FDD6680AS as the low-side switch in a synchronous rectifier is indistinguishable from the performance of the FDD6680A in parallel with a Schottky diode.
The FDD6680AS is designed to replace a single MOSFET and Schottky diode in synchronous DC/DC power supplies. It utilizes Fairchild's monolithic SyncFET technology to maximize power conversion efficiency by providing low on-resistance and low gate charge.
Key features include a maximum continuous drain current of 55A, an integrated Schottky body diode, and high performance trench technology. The device is available in the TO-252 package and is intended for use as a low-side switch in synchronous rectifier applications.
