1 / 9 page October 2006 2006 Fairchild Semiconductor Corporation FDS6994S Rev C2(W) FDS6994S Dual Notebook Power Supply N-Channel PowerTrench SyncFet™ General Description The FDS6994S is designed to replace two single SO-8 MOSFETs and Schottky diode in synchronous DC:DC power supplies that provide various peripheral voltages for notebook computers and other battery powered electronic devices. FDS6994S contains two unique 30V, N-channel, logic level, PowerTrench MOSFETs designed to maximize power conversion efficiency. The high-side switch (Q1) is designed with specific emphasis on reducing switching losses while the low- side switch (Q2) is optimized to reduce conduction losses. Q2 also includes an integrated Schottky diode using Fairchild’s monolithic SyncFET technology. Features • Q2: Optimized to minimize conduction losses Includes SyncFET Schottky body diode 8.2A, 30V R DS(on) = 15 mΩ @ VGS = 10V R DS(on) = 17.5 mΩ @ VGS = 4.5V • Q1: Optimized for low switching losses Low gate charge (85.5 nC typical) 6.9A, 30V R DS(on) = 21 mΩ @ VGS = 10V R DS(on) = 26 mΩ @ VGS = 4.5V S2 SO-8 G2 S1 G1 D2 D2 D1 D1 4 3 2 1 5 6 7 8 Q1 Q2 Absolute Maximum Ratings T A = 25°C unless otherwise noted Symbol Parameter Q2 Q1 Units VDSS Drain-Source Voltage 30 30 V VGSS Gate-Source Voltage ±16 ±16 V ID Drain Current - Continuous (Note 1a) 8.2 6.9 A - Pulsed 30 20 PD Power Dissipation for Dual Operation 2 W Power Dissipation for Single Operation (Note 1a) 1.6 (Note 1b) 1 (Note 1c) 0.9 TJ, TSTG Operating and Storage Junction Temperature Range -55 to +150 °C Thermal Characteristics RθJA Thermal Resistance, Junction-to-Ambient (Note 1a) 78 °C/W RθJC Thermal Resistance, Junction-to-Case (Note 1) 40 °C/W Package Marking and Ordering Information Device Marking Device Reel Size Tape width Quantity FDS6994S FDS6994S 13” 12mm 2500 units |
