FDD6782A
N-Channel PowerTrench® MOSFET
January 2009
25 V, 10.5 mΩ
Features
General Description
Max rDS(on) = 10.5 mΩ at VGS = 10 V, ID = 14.9 A
Max rDS(on) = 24.0 mΩ at VGS = 4.5 V, ID = 11.0 A
100% UIL test
RoHS Compliant
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.
Applications
Vcore DC-DC for Desktop Computers and Servers
VRM for Intermediate Bus Architecture
