FDMS7656AS
N-Channel PowerTrench^® SyncFET^™
30 V, 49 A, 1.8 mΩ
September 2009
Features
General Description
„ Max r_DS(on) = 1.8 mΩ at V_GS = 10 V, I_D = 30 A
„ Max r_DS(on) = 1.9 mΩ at V_GS = 7 V, I_D = 27 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
The FDMS7656AS 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 DC/DC Converters
„ Notebook Vcore/ GPU low side switch
„ Networking Point of Load low side switch
„ Telecom secondary side rectification
