Description

This reference design addresses Xilinx versal adaptive compute acceleration platform (ACAP) requirements and consists of a power management integrated circuit (PMIC) for system-rails, plus a multiphase controller and power stages to support higher current processor loads.  On-board dynamic loads on the critical outputs allow testing to Xilinx's demanding power requirements. PMP22165 along with the TPS53681 EVM is a tested solution offering performance with cost-optimized components to meet processor requirements for Versal’s most common use cases one and three. 

Features
  • 10-rail user-programmable TPS650861 PMIC for both system-level power and full design sequence management 
  • Full systempower solution for Versal's most common use cases one and three
  • Optimized power stage combination for peak efficiency of 92% on the VCCINT rail at the nominal output voltage
  • On-board dynamic loads for the more critical outputs
