November 2001

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 controller s .

These MOSFETs feature faster switching and lower
gate charge than other MOSFETs with comparable

specifications.

RDS

(ON)

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.

Features

• 3.6 A, 200 V. R

• Low gate charge

• Fast switching speed

• High performance trench technology for extremely

low R

DS(ON)

• High power and current handling capability
