AO4709
Dual 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
