FDD6672A
30V N-Channel PowerTrench MOSFET
May 2000
PRELIMINARY
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
and fast switching speed.
DS( ON)
Applications
• DC/DC converter
Features
• 65 A, 30 V. R
• High performance trench technology for extremely
low R
DS(ON)
• Low gate charge (33 nC typical)
• High power and current handling capability
