I want to estimate the maximum current ratings at AM572x power terminals to select the power ICs. Please tell me how to estimate the worst case in the AM572x Power Estimation Tool.

I particularly want to know how to determine a value input into column "Read (MB/s)" and column "Write (MB/s)".

Hi Biser-san,
Thank you for your reply.
I might have found the description, to choose either TPS6590376 and TPS6590377.
｢8.1 Power Supply Mapping｣ on datasheet (SPRS953) describes:
"These unused supplies though can be combined with any of the core supplies that are used (active) in the
system. e.g. if IVA and GPU domains are not used, they can be combined with the CORE domain,
thereby having a single power supply driving the combined CORE, IVA and GPU domains.
"
It seems that "Valid Combination 1" corresponds to TPS6590376 and "Valid Combination 2" corresponds to TPS6590377.
Therefore, when IVA and GPU domains are not used, TPS6590376 is chosen, when IVA and GPU domains are used, TPS6590377 is chosen. Is my understanding correct?
(New question)
For the AM572x Power Estimation Tool, is there the example of the typical application that is very high in power consumption?
Best regards,
Daisuke
