Welcome to the E2E forums !!!
Please refer to the Power-Supply Circuit section 3.1 in the DDC264EVM User's Guide for further details on configuring the power supply based on your need. The board was not intended to be powered by USB alone. You can provide a single power source (AC/DC wall supply) for the board with J18. To isolate the analog and digital supplies, you need to provide the supplies to J12 and J5. Please ensure all the jumpers are in the proper position for the power configuration you used. All this is explained in detail in Section 3.1, or you can refer to the EVM schematic for the jumper connections.
