Cavium CN99xx Thunder X2 CPU PMBus VDD/VDD SRAM core power design

Description

The TIDA-01367 reference design uses the TPS53679 multiphase controller and CSD95490Q5MC Smart Power Stages to implement a high-performance design suitable for powering Cavium ThunderX2® ARM Processors.The dual outputs of the controller target a 240-A: 0.8-V core rail with a six-phase design and a 20-A: 0.85-V auxiliary rail. The smart power stages and integrated PMBus™ allow for easy output voltage setting and telemetry of key design parameters. This reference design enables configuration: Vout adjustment: and compensation adjustment of the power supply: while providing monitoring of input and output voltage: current: power: and temperature.TI's Fusion Digital Power™ Designer is used for programming: monitoring: validation: and characterization of the system.

Features
  • Dual rail 6+1 design - high-powered core rail and single phase auxilliary railPMBus programming of Vout: and other IC parameters: as well as voltage marginingPMBus monitoring of input/output voltage: current: power: and temperaturePeak efficiencies of 90 and 91% for core and aux rails
