AO4812_11 Datasheet, PDF (1/5 Pages) Alpha & Omega Semiconductors – 30V Dual N-Channel MOSFET

AO4812
30V Dual N-Channel MOSFET
General Description
Product Summary
The AO4812 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 buck converters.
