AON6906A
30V Dual Asymmetric N-Channel MOSFET
General Description
Product Summary
The AON6906A 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 desgined for low R_DS(ON) to reduce conduction
losses.Power losses are minimized due to an extremely low
combination of R_DS(ON) and Crss.In addition,switching behavior
is well controlled with a "Schottky style" soft recovery body
diode.
