General Description
The AO4812A 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. AO4812A is Pb-free (meets ROHS &
Sony 259 specifications). AO4812AL is a Green
Product ordering option. AO4812A and AO4812AL
are electrically identical.
