June 1999
PRELIMINARY
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
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.
