The SP6134H is a 600kHz constant frequency, voltage mode, synchronous PWM step-down controller optimized for high efficiency.

The SP6134H is adequately suited for split plane applications utilizing a low power 5V rail to power the controller circuitry, minimizing power dissipation. Its wide input voltage range of 3V to 15V allows for conversions from the standard 3.3V, 5V, 9.6V and 12V power rails to an output voltage adjustable down to 0.8V. Developed around a wide bandwidth internal amplifier, the SP6134H can accommodate type II and type III compensation schemes.

Protection features include a programmable UVLO, thermal shutdown and output short circuit protection.

The SP6134H is part of a larger family of step-down controllers operating at various switching frequencies up to 1300kHz and input voltages up to 28V. Refer to Exar’s SP6134, SP6132, SP6132H, SP6137 and SP6139 for complete details.

The SP6134H is available in lead free, RoHS compliant, space saving 10-pin MSOP package.

  • 3V to 15V step-down achieved using dual Input
  • Small 10-PiMSOP package
  • 2A to 15A output capability
  • Highly integrated design, minimal components
  • UVLO detects both VCC and VIN
  • Short circuit protection with auto restart
  • On-board 1.5Ω sink (2Ω source) NFET drivers
  • Programmable soft-start
  • Fast transient response
  • High efficiency: greater than 94% possible
  • Asynchronous startup into a pre-charged output
