100V N-Channel PowerTrench
MOSFET
General Description
This N-Channel MOSFET has been designed
specifically to improve the overall efficiency of DC/DC
converters using either synchronous or conventional
switching PWM controllers.
These MOSFETs feature faster switching and lower
gate charge than other MOSFETs with comparable
R
DS(ON)
specifications.
The result is a MOSFET that is easy and safer to drive
(even at very high frequencies), and DC/DC power
supply designs with higher overall efficiency.
