Overview
AO4940 Asymmetric Dual N-Channel Enhancement Mode Field Effect Transistor SRFET TM General Description The AO4940 uses advanced trench technology to provide excellent RDS(ON) and low gate charge.
The two MOSFETs make a compact and efficient switch and synchronous rectifier combination for use in DC-DC converters.
A monolithically integrated Schottky diode in parallel with the synchronous MOSFET to boost efficiency further.
Standard Product AO4940 is Pb-free (meets ROHS & Sony 259 www.
