Max power requirement for i.MX6D

[jwu]

Table 9 of IMX6DQIEC lists the maximum supply currents based on a power virus.  The values are very high - higher than what the MMPF0100 is rated to provide.  We are looking to use PF0100. Is Table 15 of AN4509 a more realistic maximum to design for, or is there another recommendation? In what situation, we will see those absolute max current?

The Power Virus numbers are shown as a benchmark buy to not actually represent an actual real-situation case. Usually under this test the processor is stressed to an extreme and in normal usage you won’t ever see these numbers.

Application Note 4509 on the other hand does show actual usage scenarios so yes, you may use them for reference and adapt depending on your specific design. I would also recommend looking at the PF0100 profiles for the i.MX6 SABRE as these are set to handle tablet and smart devices scenarios efficiently and support the measured maximums shown on the application note.
