AON6906A
30V Dual Asymmetric N-Channel MOSFET
General Description
Product Summary
Q2
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 RDS(ON) to reduce conduction
losses.Power losses are minimized due to an extremely low
combination of RDS(ON) and Crss.In addition,switching behavior
is well controlled with a "Schottky style" soft recovery body
diode.
