AO4932
Asymmetric Dual N-Channel Enhancement Mode Field Effect Transistor
SRFET TM
General Description
The AO4932 uses advanced trench technology to
provide excellent R DS(ON) and low gate charge. The two
MOSFETs make a compact and efficient switch and
synchronous rectifier combination for use in DC-DC
converters. A monolithically integrated Schottky diode in
parallel with the synchronous MOSFET to boost
efficiency further. Standard Product AO4932 is Pb-free
(meets ROHS & Sony 259 specifications).
