Features
General Description
Q1: N-Channel
„ Max r_DS(on) = 21.5mΩ at V_GS = 10V, I_D = 7.5A
„ Max r_DS(on) = 29.5mΩ at V_GS = 4.5V, I_D = 6.5A
Q2: N-Channel
„ Max r_DS(on) = 13mΩ at V_GS = 10V, I_D = 10A
„ Max r_DS(on) = 17mΩ at V_GS = 4.5V, I_D = 8.5A
„ Low Qg high side MOSFET
„ Low r_DS(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
complemented by a Low Conduction Loss "Low Side" SyncFET.
Application
Synchronous Buck Converter for:
„ Notebook System Power
„ General Purpose Point of Load
„ Pinout optimized for simple PCB design
„ RoHS Compliant
