February 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.
R
DS(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
• 4.7 A, 150 V. R
• Low gate charge
• Fast switching speed
• High performance trench technology for extremely
low R
DS(ON)
• High power and current handling capability.
