FDMS3669S PowerTrench Power Stage FDMS3669S PowerTrench Power Stage General Description Asymmetric Dual N-Channel MOSFET Features This device includes two specialized N-Channel MOSFETs in a dual PQFN package. The switch node has been internally Q1: N-Channel connected to enable easy placement and routing of synchronous Max r = 10 m at V = 10 V, I = 13 A DS(on) GS D buck converters. The control MOSFET (Q1) and synchronous Max r = 14.5 m at V = 4.5 V, I = 10 A DS(on) GS D TM SyncFET (Q2) have been designed to provide optimal power Q2: N-Channel efficiency. Max r = 5 m at V = 10 V, I = 18 A DS(on) GS D Applications Max r = 5.2 m at V = 4.5 V, I = 17 A DS(on) GS D Computing Low inductance packaging shortens rise/fall times, resulting in Communications lower switching losses General Purpose Point of Load MOSFET integration enables optimum layout for lower circuit inductance and reduced switch node Notebook VCORE ringing RoHS Compliant G1 Pin 1 D1 Pin D1 D1 Q2 1 S2 D1 5 4 D1 PHAS PHAS S2 6 3 D1 E E(S1/ D2) D1 S2 7 2 G2 S2 G2 G1 S2 8 1 Q1 S2 Top Bottom Power 56 MOSFET Maximum Ratings T = 25 C unless otherwise noted A Symbol Parameter Q1 Q2 Units V Drain to Source Voltage 30 30 V DS V Gate to Source Voltage (Note 3) 20 12 V GS Drain Current -Continuous (Package limited) T = 25 C 24 60 C -Continuous (Silicon limited) T = 25 C 43 75 C I A D 1a 1b -Continuous T = 25 C 13 18 A -Pulsed (Note 6) 50 60 4 5 E Single Pulse Avalanche Energy 61 48 mJ AS 1a 1b Power Dissipation for Single Operation T = 25 C 2.2 2.5 A P W D 1c 1d Power Dissipation for Single Operation T = 25 C 1.0 1.0 A T , T Operating and Storage Junction Temperature Range -55 to +150 C J STG Thermal Characteristics 1a 1b R Thermal Resistance, Junction to Ambient 57 50 JA 1c 1d R Thermal Resistance, Junction to Ambient 125 120 C/W JA R Thermal Resistance, Junction to Case 5.0 2.8 JC Package Marking and Ordering Information Device Marking Device Package Reel Size Tape Width Quantity 9ACF FDMS3669S Power 56 13 12 mm 3000 units 21CD 2013 Semiconductor Components Industries,LLC Publication Order Number: August-2017,Rev.3 FDMS3669S/D
