AO4444
N-Channel Enhancement Mode Field Effect Transistor
General Description
The AO4444 uses advanced trench technology to
provide excellent R_DS(ON), body diode characteristics
and ultra-low gate resistance. This device is ideally
suited for use as a low side switch in 12V buck
converters. Standard Product AO4444 is Pb-free
(meets ROHS & Sony 259 specifications). AO4444L
is a Green Product ordering option. AO4444 and
AO4444L are electrically identical.
