The NXP® MC34713 is a highly integrated, space efficient, low cost, single synchronous buck switching regulator with integrated N-channel power MOSFETs.

  • It is a high performance point-of-load (PoL) power supply with the ability to track an external reference voltage in different configurations
  • High efficient 5.0 A continuous output current capability, combined with voltage tracking/sequencing and tight output regulation, makes it ideal as a single power supply
  • Offers flexibility of many control, supervisory, and protection functions to allow for easy implementation of complex designs
