Reference Design for Powering a Xilinx Zynq UltraScale+ Remote Radio Head (RRH) or Backhaul (BH)

Overview

TopologyBuck Converter
Input voltage27 V
Output 11.24 V / 3 A
IC revision1

Description

This design for powering Xilinx Zynq UltraScale+ (www.xilinx.com/power) Remote Radio Heads (RRH) features the TPS6508640 and is a small and highly efficient solution. The PMIC reduces size, cost, and power loss by having integrated rails into 1 device, high switching frequency and separate rails for core supplies.

Features

  • PMIC reduces solution size by integrating many rails into 1 device
  • PMIC reduces inductor size by having high switching frequency converters and controllers
  • Separation of core option saves power with estimated 2.6W at max loading
  • DVS allows for higher power savings by reducing the output power for lower operational needs
