FDS6994S September 2002 FDS6994S ™ Dual Notebook Power Supply N-Channel PowerTrench SyncFet General Description Features The FDS6994S is designed to replace two single SO-8 • Q2: Optimized to minimize conduction losses MOSFETs and Schottky diode in synchronous DC:DC Includes SyncFET Schottky body diode power supplies that provide various peripheral voltages 8.2A, 30V R = 15 mΩ @ V = 10V DS(on) GS for notebook computers and other battery powered electronic devices. FDS6994S contains two unique R = 17.5 mΩ @ V = 4.5V DS(on) GS 30V, N-channel, logic level, PowerTrench MOSFETs designed to maximize power conversion efficiency. • Q1: Optimized for low switching losses Low gate charge (85.5 nC typical) The high-side switch (Q1) is designed with specific emphasis on reducing switching losses while the low- 6.9A, 30V R = 21 mΩ @ V = 10V DS(on) GS side switch (Q2) is optimized to reduce conduction R = 26 mΩ @ V = 4.5V losses. Q2 also includes an integrated Schottky diode DS(on) GS using Fairchild’s monolithic SyncFET technology.
