Xilinx Virtex UltraScale FPGA Power Solution with PMBus Reference Design


Design files


The PMP9475 12V-input reference design provides all the power supply rails necessary to power Xilinx's Virtex® UltraScale™ family of FPGAs in  a compact, highly efficient design.  This design uses several of TI's PMBus Point-Of-Load voltage regulators for ease of design/configuration and telemetry of critical rails. It features a UCD90120A for flexible power up and power down sequencing as well as voltage monitoring, current monitoring, and voltage margining through the PMBus interface.

  • Provides all the power supply rails needed for a Xilinx Virtex® UltraScale™ FPGA
  • Design optimized to support a 12V input
  • On board power up and power down sequencing
  • PMBUS interface with output voltage and current reporting
  • Voltage margining feature
