Reference Design for Powering a Xilinx Zynq UltraScale+ Remote Radio Head (RRH) or Backhaul (BH)
Overview
| Topology | Buck Converter |
| Input voltage | 27 V |
| Output 1 | 1.24 V / 2 A |
| IC revision | 1 |
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
