Hello.

I have a question about PDN design for AM69A processor. Is it possible not to use TPS6594 PMIC if I don't need any functional safety for my device? Can I use a bunch of simple DCDCs instead? I just ould like to simplify my design.

    That is possible but not recommended.  The processor has been tested with the PMIC, and thus has validated its load step response, noise levels, power rail sequence control, etc. with the processor.  I'm not sure using a bunch of discrete supplies and sequencer would be simplified.
