General Description
This P-Channel MOSFET has been designed specifically to
improve the overall efficiency of DC/DC converters using either
synchronous or conventional switching PWM controllers, and
battery chargers.
These MOSFETs feature faster switching and lower gate
charge than other MOSFETs with comparable R
DS(ON)
specifi-
cations.
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.
