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 resulting in DC/DC power supply designs

with higher overall efficiency.
