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 com specifications).
