PROCESSOR-SDK-AM62A: PMIC setup understanding

Evan

Part Number: PROCESSOR-SDK-AM62A
Other Parts Discussed in Thread: SK-AM62-LP, TPS6594-Q1

I have an own design with AM62A and am trying to establish how to configure the PMIC.

Referring to SLVUCM3 – TPS65931211-Q1 PMIC User Guide for AM62A, it does not seem to contain a list of appropriate settings for use with AM62A, only the default ones.

How is the PMIC normally initialized in the SK-AM62-LP design for example? Is this described somewhere?

Thank you.

Hi Evan

I am routing this thread to our PMIC product group.

Thanks. To follow up - I did not realize that the default settings of TPS65931211 part are in fact pre-programmed already for use with the AM62A SoC.

My actual situation is that I am using TPS6594-Q1 which is not pre-programmed, so I attempt to recover the register settings from this document and apply them to the TPS6594. edit: I also read out the values from the TPS65931211-Q1 part on the EVK, and there are only small differences.

So far it at least tries to start, I have some errors relating to the multi-phase output. I start a new thread for that. https://e2e.ti.com/support/power-management-group/power-management/f/power-management-forum/1288411/tps6594-q1-startup-failing
