AO4844

Dual N-Channel Enhancement Mode Field Effect Transistor

General Description

Features

The AO4844 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 buck

converters. AO4844 is Pb-free (meets ROHS & Sony

259 specifications). AO4844L is a Green Product

ordering option. AO4844 and AO4844L are

electrically identical.

V_DS(V) = 30V

I_D= 6.9A

(V_GS= 10V)

_DS(ON)< 28mΩ (V_GS= 10V)

R_DS(ON)< 42mΩ (V_GS= 4.5V)
