AO4709
P-Channel Enhancement Mode Field Effect Transistor
with Schottky Diode
General Description
The AO4709 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
AO4709 is Pb-free (meets ROHS & Sony 259
specifications). AO4709L is a Green Product ordering
option. AO4709 and AO4709L are electrically identical.
