AO4932 Datasheet, PDF (1/9 Pages) Alpha & Omega Semiconductors – Asymmetric Dual N-Channel Enhancement Mode Field Effect Transistor

AO4932
Asymmetric Dual N-Channel MOSFET
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.
