Versal AI Core XCVC1902
Edge Core FPGA Power Delivery Reference Design
Top
Overview
Features & Benefits
The ADI Versal AI Core Power Reference Design Board has been tested and proven to power the key rails for the Xilinx Versal AI Core ACAP series. Using a PMBUs Multi Phase DC/DC controller coupled with ADI SilentMOS (ADI version of DrMOS) to deliver up to 240A of output current.
The ADI LTC3888-1 is an 8 Phase PMBUs DC/DC controller that is coupled with the LTC7051 ADI SilentMOS to provide a flexible and scalable design that can be tailored as needed for both higher and lower power applications by adding or subtracting the LTC7051 ADI SilentMOS.
