30V, 121A, 4.7m鈩?/div>
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
DS(ON)
and fast switching speed.
