General Description
Q1: N-Channel
Max rDS(on) = 8.5mΩ at VGS = 10V, ID = 12A
Max rDS(on) = 12.4mΩ at VGS = 4.5V, ID = 10A
Q2: N-Channel
Max rDS(on) = 5.5mΩ at VGS = 10V, ID = 16A
Max rDS(on) = 7.0mΩ at VGS = 4.5V, ID = 14A
Low Qg high side MOSFET
Low rDS(on) low side MOSFET
Thermally efficient dual Power 56 package
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 com-
plemented by a Low Conduction Loss "Low Side" SyncFET.
Applications
Synchronous Buck Converter for:
Notebook System Power
General Purpose Point of Load
Pinout optimized for simple PCB design
RoHS Compliant
