General Description
These N Channel Logic Level MOSFET have been
designed specifically to improve the overall efficiency of
DC/DC converters using either synchronous or
conventional switching PWM controllers.
The MOSFET feature faster switching and lower gate
charge than other MOSFET with comparable RDS(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.
