Smart Power Stage (SPS) Module Family

Unequaled power density for DC-DC designs from Fairchild Semiconductor

Image of Fairchild's Smart Power Stage (SPS) Module FamilyFairchild Semiconductor's smart power stage (SPS) module family is a next-generation, ultra-compact, integrated MOSFET plus driver-power stage solution. 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 in high-performance computing and telecom.

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 high-performance PowerTrench® MOSFET technology to reduce ringing, eliminating the need for a snubber circuit in most buck converter applications.

Features

  • Ultra-compact 5 mm x 5 mm x 0.8 mm PQFN with Dual Cool™ packaging technology
  • Three-state 3.3 V PWM and 5 V PWM input gate driver
  • Integrated Zero Cross Detect (ZCD) or FCCM circuitry for better light load efficiency
  • Dual-mode enable and catastrophic fault reporting pin
  • Under-voltage lockout (UVLO) protection
  • Optimized for switching frequencies, up to 2 MHz
  • Low shutdown current < 3 μA
  • Improved power stage dynamic performance, system inductance
  • PowerTrench® MOSFET technology to reduce ringing, eliminate snubber in most buck converter designs
  • Thermal monitoring, programmable thermal shutdown

Applications

  • Notebook, tablet PC, and ultrabook
  • Servers and workstations, VCORE and non-VCORE DC-DC converters
  • Desktop and all-in-one computers, VCORE and non-VCORE DC-DC converters
  • High-performance gaming motherboards
  • High-current DC-DC point-of-load converters
  • Networking and telecom microprocessor voltage regulators
  • Small form-factor voltage regulator modules
