AO4408, AO4408L (Green Product)
N-Channel Enhancement Mode Field Effect Transistor
General Description
The AO4408 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.
AO4408L(Green Product) is offered in a lead-free
package.
