FDS7764A
30V N-Channel PowerTrench
MOSFET
General Description
This
specifically to improve the overall efficiency of DC/DC
converters using either synchronous or conventional
switching PWM controllers. It has been optimized for
“low side” synchronous rectifier operation, providing an
extremely low R
DS(ON)
in a small package.
