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.
