AO4938

30V Dual N-Channel MOSFET

General Description

excellent R_DS(ON)and low gate charge. The two MOSFETs

rectifier combination for use in DC-DC converters. A

The AO4938 uses advanced trench technology to provide

make a compact and efficient switch and synchronous

monolithically integrated Schottky diode in parallel withthe synchronous MOSFET to boost efficiency further.
