30A PMBus Reference Design for Xilinx Zynq Ultrascale+ ZU9EG MPSoC Core Rail for Base Stations
Description
The PMP11328 is a high power density 30A PMBus power supply meeting the Xilinx Ultrascale+ ZU9EG FPGA core rail power specifications for Base Station Remote Radio Unit (RRU) applications. The power supply regulates 0.85V for the core rail at 25A in 55mm x 40mm total power supply PCB area. PMBus capability enables easy programming: and custom configuration of the power supply through on-board Non-Volatile Memory (NVM): as well easy Adaptive Voltage Scaling (AVS): and Voltage Margining. The power supply also enables monitoring of the output voltage: current: and external hot spot temperature through PMBus. Overall ±3% tolerance is met while efficiency is >82%.
Features
- 12V input: 0.85V/25A PoL in 40mm x 55mm PCB areaHigh efficiency >82% at 0.85V/25A: 500kHzAdaptive Voltage Scaling (AVS): Voltage Margining: and Output Voltage/Current/Temperature monitoring through PMBus and TI's Fusion GUI4W Power Loss at 12VIN: 0.85V/25A12mV overshoot/undershoot during a 8A load transient at 10A/µs±3% total load regulation (AC and DC)
