FDN372S
30V N-Channel PowerTrench SyncFETTM
General Description
The FDN372S is designed to replace a single MOSFET and Schottky diode, used in synchronous DC-DC power supplies, with a single integrated component. This 30V MOSFET is designed to maximize power conversion efficiency with low Rds(on) and low gate charge. The FDN372S includes an integrated Schottky diode using Fairchild Semiconductor s monolithic SyncFET process, making it ideal as the low side switch in a synchronous converter.

Features
2.6 A, 30 V. RDS(ON) 40 m VGS 10 V RDS(ON) 50 m VGS 4.5 V

Low gate charge Fast switching speed High performance trench technology for extremely low RDS(ON)

Applications
DC-DC Converter Motor Drives
