AON6908A Datasheet, PDF (1/11 Pages) Alpha & Omega Semiconductors – 30V Dual Asymmetric N-Channel MOSFET

AON6908A
30V Dual Asymmetric N-Channel MOSFET
General Description
Product Summary
The AON6908A 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 desgined to minimze switching losses.
The Q2 "Low Side" MOSFET is an SRFET™ that features
low R_DS(ON) to reduce conduction losses as well as an
integrated Schottky diode with low Q_RR and V_f to reduce
switching losses. The AON6908A is well suited for use in
compact DC/DC converter applications.
