6690AS

FDS6690AS 30V N-Channel PowerTrench® SyncFET™ May 2008 FDS6690AS 30V N-Channel PowerTrench® SyncFET™ General Description The FDS6690AS is designed to replace a single SO-8 MOSFET and Schottky diode in synchronous DC:DC power supplies. This 30V MOSFET is designed to maximize power conversion efficiency, providing a low RDS(ON) and low gate charge. The FDS6690AS includes an integrated Schottky diode using Fairchild’s monolithic SyncFET technology. The performance of the FDS6690AS as the low-side switch in a synchronous rectifier is close to the performance of the FDS6690A in parallel with a Schottky diode. tm Features 10 A, 30 V. RDS(ON) max= 12 mΩ @ VGS = 10 V RDS(ON) max= 15 mΩ @ VGS = 4.5 V Includes SyncFET Schottky diode Low gate charge (16nC typical) High performance trench technology for extremely low RDS(ON) High power and current handling capability Applications DC/DC converter Low side notebooks D D D D 5 6 4 3 2 1 SO-8 S S S G 7 8 Absolute Maximum Ratings Symbol VDSS VGSS ID PD Drain-Source Voltage Gate-Source Voltage Drain Current – Continuous – Pulsed TA=25oC unless otherwise noted Parameter Ratings 30 ±20 (Note 1a) Units V V A W 10 50 2.5 1.2 1 –55 to +150 Power Dissipation for Single Operation (Note 1a) (Note 1b) (Note 1c) TJ, TSTG Operating and Storage Junction Temperature Range °C Thermal Characteristics RθJA RθJC Thermal Resistance, Junction-to-Ambient Thermal Resistance, Junction-to-Case (Note 1a) (Note 1) 50 25 °C/W °...
