General Description
This device includes two specialized MOSFETs in a unique dual
Power 56 package. It is designed to provide an optimal synchro-
nous buck power stage in terms of efficiency and PCB utilization.
The low switching loss “High Side” MOSFET is complementory
by a low conduction loss “Low Side” SyncFET.
Applications
Synchronous Buck Converter for:
„ Notebook System Power
„ General Purpose Point of Load
