FDS7064SN3 Datasheet | Fairchild Semiconductor

February 2004 30V N-Channel PowerTrench SyncFET™ General Description The FDS7064SN3 is designed to improve the efficiency of Buck Regulators. Used as the Synchronous rectifier, (Low side MOSFET), losses can be reduced, not only in this device, but also in the Control switch, (High side MOSFET). After the low side MOSFET turns off, reverse recovery current in the body diode is dissipated in the High Side device. A Discrete Schottky diode in parallel with the Low Side MOSFET can lower the reverse recovery current, but parasitic PCB and Package Inductance reduce the effectiveness of the TM technology reduces this Schottky. SyncFET inductance to a minimum by providing...
