FDD8770/FDU8770
N-Channel PowerTrench® MOSFET
25V, 35A, 4.0mΩ
AD FREE I
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
rDS(on) and fast switching speed.
Application
Features
„ Max rDS(on) = 4.0mΩ at VGS = 10V, ID = 35A
„ Max rDS(on) = 5.5mΩ at VGS = 4.5V, ID = 35A
„ Low gate charge: Qg(10) = 52nC(Typ), VGS = 10V
„ Low gate resistance
„ RoHS Compliant
„ Vcore DC-DC for Desktop Computers and Servers
„ VRM for Intermediate Bus Architecture
