FDMS7558S
N-Channel PowerTrench® SyncFETTM
25 V, 49 A, 1.25 m
December 2009
Features
„ Max rDS(on) = 1.25 mat VGS = 10 V, ID = 32 A
„ Max rDS(on) = 1.75 mat VGS = 4.5 V, ID = 28 A
„ Advanced Package and Silicon combination for low rDS(on)
and high efficiency
„ SyncFET Schottky Body Diode
„ MSL1 robust package design
„ 100% UIL tested
„ RoHS Compliant
General Description
The FDMS7558S has been designed to minimize losses in
power conversion application. Advancements in both silicon and
package technologies have been combined to offer the lowest
rDS(on) while maintaining excellent switching performance. This
device has the added benefit of an efficient monolithic Schottky
body diode.
Applications
„ Synchronous Rectifier for Synchronous Buck Converters
„ Notebook
„ Server
„ Telecom
„ High Efficiency DC-DC Switch Mode Power Supplies
