Power reference design for Xilinx® Zynq® UltraScale+™ MPSoC applications


Design files


This reference design is a configurable power solution designed to handle the entire Xilinx® Zynq® UltraScale+ (ZU+) family of MPSoC devices across various use cases.

The various versions of the TPS65086x PMIC allow this design to power devices from the basic ZU2CG device with a dual-core Arm® Cortex®-A53 application processor and dual-core Arm Cortex-R5 real-time processor to the higher end ZU7EV, ZU19EG and ZU21DR devices, which add other components to the MPSoC such as a graphics processing unit, video Codec unit and up to 16 16.3- Gbps transceivers.

This design includes many additional components that can be used with the TPS65086x device such as external load switches, pre-regulators, and a push button circuit.

  • 10 programmable output rails – 3 BUCK converters, 3 BUCK controllers, 3 LDOs, 1 VTT LDO for DDR memory termination
  • 5 load switches – 3 internal to TPS65086x device, 2 external TPS22920 load switches
  • Wide input voltage range (5 V to 24 V)
  • 4 GPOs
  • Sequencing control with 6 CTL pins, or I²C
