Description

This FDT3612 N-Channel MOSFET has been designed specifically to improve the overall efficiency of DC/DC converters using either synchronous or conventional switching PWM controllers.

These FDT3612 MOSFETs 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.
