Smart Power Stage (SPS) Product Family Brief0 pages

Smart Power Stage (SPS) Portfolio
Next-Generation, Multi-Chip Module
The SPS module family is a next-generation, ultra-compact, integrated MOSFET plus driver power stage
solution. Compared to competitive modules, the family offers three-percent greater efficiency, unique
monitoring and protection features, all in 33-percent less space. This family leverages Fairchild’s DrMOS
expertise to deliver high efficiency, high-power density and high-switching frequency in applications such
as synchronous buck DC-DC converters for high-performance computing and telecom systems.
With an integrated approach, the complete switching power stage is optimized for driver and MOSFET
dynamic performance, system inductance and power MOSFET RDS(ON). SPS modules use our highperformance PowerTrench® MOSFET technology to reduce ringing, eliminating the need for a snubber
circuit in most buck converter applications.
