Texas Instruments TPS650864 | Demoboard PMP12004-HE
Powering Xilinx™ Zynq® UltraScale+™ Based Remote Radio Head (RRH) or Backhaul (BH) Reference Design
Overview
| Topology | Buck Converter |
| Input voltage | 5.6-21 V |
| Output 1 | 1.85 V / 1 A |
| IC revision | A |
Description
The function of the PMP12004-HE TI Design is to provide a solution for the power supply of Xilinx Zynq® UltraScale+™ based remote radio heads (RRH). This power design only requires two regulator devices: the TPS6508640 power management integrated circuit (PMIC) and the TPS544C25 high-current, singlechannel device. Using these devices reduces size, cost, and power loss by featuring integrated rails, high switching frequency, and separate rails for the core supplies. This design guide addresses the following topics: RRH power solutions and designing for maximum efficiency.
Features
- PMIC Reduces Solution Size by Integrating Several Rails Within Single Device
- PMIC Reduces Inductor Size by Having High Switching Frequency Converters and Controllers
- Separation of Core Option Saves Power With Estimated 2.6 W at Max Loading
- DVS Allows For Higher Power Savings by Reducing Output Power for Lower Operational Requirements
Typical applications
- Remote Radio Head (RRH),Wireless Backhaul (BH)
