FDMS3664S  
PowerTrench® Power Stage  
Asymmetric Dual N-Channel MOSFET  
Features  
General Description  
Q1: N-Channel  
This device includes two specialized N-Channel MOSFETs in a  
dual PQFN package. The switch node has been internally  
connected to enable easy placement and routing of synchronous  
buck converters. The control MOSFET (Q1) and synchronous  
SyncFET (Q2) have been designed to provide optimal power  
efficiency.  
„ Max rDS(on) = 8 mΩ at VGS = 10 V, ID = 13 A  
„ Max rDS(on) = 11 mΩ at VGS = 4.5 V, ID = 11 A  
Q2: N-Channel  
„ Max rDS(on) = 2.6 mΩ at VGS = 10 V, ID = 25 A  
„ Max rDS(on) = 3.2 mΩ at VGS = 4.5 V, ID = 22 A  
Applications  
„ Low inductance packaging shortens rise/fall times, resulting in  
„ Computing  
lower switching losses  
„ MOSFET integration enables optimum layout for lower circuit  
inductance and reduced switch node ringing  
„ Communications  
„ General Purpose Point of Load  
„ Notebook VCORE  
„ RoHS Compliant
