The AON6912A is designed to provide a high efficiency
synchronous buck power stage with optimal layout and
board space utilization. It includes two specialized
MOSFETs in a dual Power DFN5x6 package. The Q1
"High Side" MOSFET is designed to minimize switching
losses. The Q2 "Low Side" MOSFET is designed for low
R
to reduce conduction losses. The AON6912A is
DS(ON)
well suited for use in compact DC/DC converter
applications.
