AOD478/AOI478
100V N-Channel MOSFET
General Description
The AOD478/AOI478 combines advanced trench
MOSFET technology with a low resistance package to
provide extremely low RDS(ON). This device is ideal for
boost converters and synchronous rectifiers for
consumer, telecom, industrial power supplies and LED
backlighting.
