The NXP® MC34712 is a highly-integrated, space-efficient, low-cost, single-synchronous buck switching regulator with integrated N-channel power MOSFETs.

  • High performance point-of-load (PoL) power supply with the ability to track an external reference voltage
  • Its high efficient 3 A sink and source capability combined with its voltage tracking/sequencing ability and tight output regulation makes it ideal to provide the termination voltage for modern data buses such as DDR memory buse
  • Provides a buffered output VREF to the memory chipset
  • Offers flexibility of many control, supervisory, and protection functions to allow for easy implementation of complex designs
