Description

These FDS3912 N-Channel MOSFETs have been designed specifically to improve the overall efficiency of DC/DC converters using either synchronous or conventional switching PWM controllers.These MOSFETs FDS3912 feature faster switching and lower gate charge than other MOSFETs with comparable R _DS(ON) specifications. 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.
