The NXP® MC34716 is a highly integrated, space-efficient, low cost, dual synchronous buck switching regulator with integrated N-channel power MOSFETs.

  • High performance point-of-load (PoL) power supply with its second output having the ability to track an external reference voltage
  • Provides a full power supply solution for DDR memories
  • Channel one provides a source only 5 A drive capability, channel two can sink and source up to 3 A; both are highly efficient with tight output regulation
  • Has a buffered output reference voltage to the memory chipset
  • Offers flexibility of many control, supervisory, and protection functions to allow for easy implementation of complex designs
