AO4703
P-Channel Enhancement Mode Field Effect Transistor
with Schottky Diode
General Description
The AO4703 uses advanced trench technology to
provide excellent R
DS(ON)
and low gate charge. A
Schottky diode is provided to facilitate the
implementation of non-synchronous DC-DC
converters.
Standard Product AO4703 is Pb-free
(meets ROHS & Sony 259 specifications). AO4703L
is a Green Product ordering option. AO4703 and
AO4703L are electrically identical.
