3.4.3.4 Power Supply

The EVM utilizes an array of DC-DC converters to supply the various memories, clocks, SoC and other components on the card with the necessary voltage and the power required. Table 3-5 gives power-good LEDs provided on EVM board to give users positive confirmation of the status of output of each supply.

Test points for each power outputs are provided on the EVM Board and are mentioned in the below Table 3-4.
