MOSFET  
General Description  
Features  
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)
, fast switching speed and  
extremely low R

DS(ON)

in a small package.
