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