FDMS7578
N-Channel Power Trench® MOSFET
25 V, 5.8 m
Features
General Description
„ Max rDS(on) = 5.8 mat VGS = 10 V, ID = 17 A
„ Max rDS(on) = 8 mat VGS = 4.5 V, ID = 14 A
„ Advanced Package and Silicon combination for low rDS(on)
and high efficiency
„ Next generation enhanced body diode technology, engineered
for soft recovery
„ MSL1 robust package design
This N-Channel MOSFET has been designed specifically to
improve the overall efficiency and to minimize switch node
ringing of DC/DC converters using either synchronous or
conventional switching PWM controllers. It has been optimized
for low gate charge, low rDS(on), fast switching speed and body
diode reverse recovery performance.
Applications
„ Control MOSFET for Synchronous Buck Converters
„ 100% UIL tested
„ Notebook
„ RoHS Compliant
„ Server
„ Telecomm
„ High Efficiency DC-DC Switch Mode Power Supplies
