FDS6982AS December 2006 FDS6982AS General Description The FDS6982AS is designed to replace two single SO8 MOSFETs and Schottky diode in synchronous DC:DC power supplies that provide various peripheral voltages for notebook computers and other battery powered electronic devices. FDS6982AS 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. tm Dual Notebook Power Supply N-Channel PowerTrench SyncFET Features Q2: Optimized to minimize conduction losses Includes SyncFET Schottky body diode RDS(on) max= 13.5m @ VGS = 10V RDS(on) max= 16.5m @ VGS = 4.5V 8.6A, 30V Low gate charge (21nC typical) Q1: Optimized for low switching losses RDS(on) max= 28.0m @ VGS = 10V RDS(on) max= 35.0m @ VGS = 4.5V 6.3A, 30V Applications Notebook Low gate charge (11nC typical) D1 D1 D2 D2 S1 G1 5 6 7 Q1 4 3 2 Q2 SO-8 S2 8 1 G2 Absolute Maximum Ratings Symbol VDSS VGSS ID PD Drain-Source Voltage Gate-Source Voltage Drain Current TA = 25°C unless otherwise noted Parameter Q2 30 (Note 1a) Q1 30 ±20 6.3 20 2 1.6 1 0.9 –55 to +150 Units V V A W - Continuous - Pulsed Power Dissipation for Dual Operation Power Dissipation for Single Operation ±20 8.6 30 (N……
