AM3894 Power Rail Sharing Details Request

Other Parts Discussed in Thread: AM3894

Hi,

There are many power supply terminal with common voltage(3.3V, 1.5V, 1.8V......) for AM3894.

Is there any power supply guidelines that provides details of sharing power supply terminal with common voltage rail and what type of regulator to be selected?

Or we need to only refer reference schematics (NETRA EVM) for above requirement?

Please suggest.

Regards,

SMK

    Hi Sachin,

    I made a search but I did not find any specific guidelines for sharing power supply with common voltage rail.

    Besides the reference schematics of the Netra (DM816X/AM389X) EVM, you can also find some info in:

    AM389X TRM: chapter 3 Power Management, section 18.1.4 Power Management, and section 18.6 Power Management.

    AM389X datasheet, section 7.1 7.1 Power Supplies
