AO3442
100V N-Channel MOSFET
General Description
The AO3442 combines advanced trench MOSFET
technology with a low resistance package to provide
extremely low R
DS(ON)
. This device is ideal for boost
converters and synchronous rectifiers for consumer,
telecom, industrial power supplies and LED backlighting.
