AON6912A
30V Dual Asymmetric N-Channel MOSFET
General Description
Product Summary
Q1
Q2
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
RDS(ON) to reduce conduction losses. The AON6912A is
well suited for use in compact DC/DC converter
applications.
