... General Description The AO4932 uses advanced trench technology to provide excellent R and low gate charge. The two MOSFETs DS(ON) 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. ...
