FDS9945 60V N-Channel PowerTrench? MOSFET General Description These N Channel Logic Level MOSFET have been designed specifically to improve the overall efficiency of DC/DC converters using either synchronous or conventional switching PWM controllers. The MOSFET feature faster switching and lower gate charge than other MOSFET with comparable RDS(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. Features • 3.5 A, 60 V. RDS(ON) = 0.100? @ VGS = 10 V RDS(ON) = 0.200? @ VGS = 4.5V • Optimized for use in switching DC/DC converters with PWM controllers • Very fast switching • Low gate charge.
