General Description
The AO4918 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. A Schottky diode is co-packaged in parallel
with the synchronous MOSFET to boost efficiency further
Standard Product AO4918 is Pb-free (meets ROHS &
Sony 259 specifications). AO4918L is a Green Product
ordering option. AO4918 and AO4918L are electrically
identical.
