AO4918A

Asymmetric Dual N-Channel Enhancement Mode Field Effect

Transistor

General Description

Features

The AO4918A 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.AO4918A is Pb-free (meets ROHS

& Sony 259 specifications). AO4918AL is a Green

Product ordering option. AO4918A and AO4918AL

are electrically identical.
