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.
