Description

This reference design demonstrates how the required power rails for the VE2302 device can be powered by TI's regulator ICs. See AMD’s Power Design Manager (PDM) tool, for all available power consolidation options. Use PDM when estimating power for any application. This reference design uses example power estimations. The design can also be used as a foundation for designing the power tree for other devices of the AI Edge series. The original power source for this system is typically between 8VIN to 18VIN and capable of delivering about 50W of power.
