AO4408
N-Channel Enhancement Mode Field Effect Transistor
General Description
The AO4408/L uses advanced trench technology to
provide excellent R_DS(ON), low gate charge and fast
switching. This device makes an excellent high side
switch for notebook CPU core DC-DC conversion.
AO4408 and AO4408L are electrically identical.
-RoHS Compliant
-AO4408L is Halogen Free
