FDS6990AS
Dual 30V N-Channel PowerTrench® SyncFET™
March 2010
Features
■ 7.5 A, 30 V. RDS(ON) = 22 mΩ @ VGS = 10 V
RDS(ON) = 28 mΩ @ VGS = 4.5 V
■ Includes SyncFET Schottky diode
■ Low gate charge (10nC typical)
■ High performance trench technology for extremely low
RDS(ON)
■ High power and current handling capability
Applications
■ DC/DC converter
■ Motor drives
General Description
The FDS6990AS is designed to replace a dual SO-8 MOSFET
and two Schottky diodes in synchronous DC:DC power sup-
plies. This 30V MOSFET is designed to maximize power con-
version efficiency, providing a low RDS(ON) and low gate charge.
Each MOSFET includes integrated Schottky diodes using Fair-
child’s monolithic SyncFET technology. The performance of the
FDS6990AS as the low-side switch in a synchronous rectifier is
similar to the performance of the FDS6990A in parallel with a
Schottky diode.
