The thermal images in Figure 3-18 and Figure 2-8 show operation at 12-V input and maximum current for each output rail on the highest power AM62x processor with no airflow after the board had reached thermal equilibrium. Figure 3-18 is a thermal image when the VDD_CORE was 0.75 V with an output current of 5.7 A. Figure 2-8 shows a thermal image when VDD_CORE was 0.85 V with an output current of 6.9 A.
