FDS7064A
30V N-Channel PowerTrench MOSFET
May 2000
ADVANCE INFORMATION
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 side” synchronous rectifier operation, providing an
extremely low R
in a small package.
