AO4406 Datasheet, PDF (1/7 Pages) Alpha Industries – N CHANNEL ENHANCEMENT MODE FIELD EFFECT TRANSISTOR

AO4406
N-Channel Enhancement Mode Field
Effect Transistor
General Description
The AO4406 uses advanced trench technology to provide excellent R_DS(ON) , low gate charge and
operation with gate voltages as low as 2.5V. This device makes an excellent high side switch for
notebook CPU core DC-DC conversion.
