25 V, 49 A, 1.25 mΩ
December 2009
Features
„ Max r_DS(on) = 1.25 mΩ at V_GS = 10 V, I_D = 32 A
„ Max r_DS(on) = 1.75 mΩ at V_GS = 4.5 V, I_D = 28 A
„ Advanced Package and Silicon combination for low r_DS(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
r_DS(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
