AON6926
30V Dual Asymmetric N-Channel MOSFET
General Description
Product Summary
Q2
Q1
The AON6926 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 DFN5x6A package. The Q1
"High Side" MOSFET is desgined to minimze switching
losses. The Q2 "Low Side" MOSFET is an SRFET™ that
features low RDS(ON) to reduce conduction losses as well as
an integrated Schottky diode with low QRR and Vf to reduce
switching losses. The AON6926 is well suited for use in
compact DC/DC converter applications.
