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. It has
been optimized for low gate charge, low r
DS(on)
and fast
switching speed.
Applications
 Vcore DC-DC for Desktop Computers and Servers
 VRM for Intermediate Bus Architecture
