Overview

This reference design features multiple TPS54325 and other power devices for Xilinx Zynq FPGA. From 12-V input, this reference design has the power rails required by Zynq FPGA, including DDR3 memory.

Features
  • Provides power rails needed for Zynq FPGA
  • Operates with wide input voltage range 5 V to 12 V
  • Very high density PCB design that saves board area
  • Supports DDR3 memory device
  • Power distribution tree with a combination of switching regulators and LDO
  • Tested and ready to power-up Zynq FPGA
