AO4918

Asymmetric Dual N-Channel Enhancement Mode Field Effect

Transistor

General Description

Features

The AO4918 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 Schottky diode is co-packaged in parallel

with the synchronous MOSFET to boost efficiency further

Standard Product AO4918 is Pb-free (meets ROHS &

Sony 259 specifications). AO4918L is a Green Product

ordering option. AO4918 and AO4918L are electrically

identical.
