The SP6132H is a synchronous step-down switching regulator controller optimized for high efficiency. The part is designed to be especially attractive for dual supply, 12V step-down with 5V used to power the controller. This lower VCC voltage minimizes power dissipation in the part. The SP6132H is designed to drive a pair of external NFETs using a fixed 300kHz frequency, PWM voltage mode architecture. Protection features include UVLO, thermal shutdown and output short-circuit protection. The SP6132H is available in the cost and space saving 10-pin MSOP.

  • 3V to 15V step-down achieved using dual input
  • Onboard 1.5Ω sink (2Ω source) NFET drivers
  • Up to 30A output capability
  • Highly integrated design, minimal components
  • UVLO detects both VCC and VIN
  • Short-circuit protection with auto restart
  • Wide BW Amp allows type II or III compensation
  • Programmable soft-start
  • Fast transient response
  • High efficiency: greater than 95% possible
  • A synchronous startup into a pre-charged output
  • Small 10-Pin MSOP package

  • Wireless Base Station
  • Automotive
  • Industrial
  • Power Supply
