Description :

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.
