AO4854 Datasheet, PDF (1/6 Pages) Alpha & Omega Semiconductors – 30V Dual N-channel MOSFET

AO4854
30V Dual N-channel MOSFET
General Description
Product Summary
The AO4854 uses advanced trench technology to provide
excellent R_DS(ON) and low gate charge. The two MOSFETs
make a compact and efficient switch and synchronous
rectifier combination for use in DC-DC converters.
