TPS6594-Q1: Which part to use with the TDA4VL?

Ishtiaque,

Thanks for getting back to me!  Is this a space optimized design recommendation?  Space is my biggest concern.  That is why I was looking at a design with a single TPS6594-Q1.  I am not concerned about low power modes, or independent power control.

Thanks,

Brian

Sorry.  I realized I had the wrong link above.  This is the guide I was hoping to use: https://www.ti.com/lit/pdf/slvucd4

Hi Brain,

Since you mentioned TDA4VL so that's why I directed to the associated user guide to look into. 

I do not have have much insight into how much optimized design is but surely with PMICs we try to keep the designs as optimized as possible. 

Looping @n-mcnamara@ti.com to provide his opinion on design optimization question.

Hello Brian,

So for the TDA4VL (J721S2) we have a singular PMIC solution, you can find the guide for that here Powering Jacinto TM J7 SoC Family For Isolated Power Groups With TPS6594133A-Q1 PMIC and Dual HCPS Converters

We recommend PDN-3X for newer builds, the suffix 'X' represents features that can be added or removed for cost / software complexity.

For the sake of simplicity it looks like PDN-3M or PDN-3G would be more fitting as low power modes / split grouping (fall back to MCU mode) isn't a concern.

These PDNs remove extra discrete devices which would take up precious PCB space.

Please let me know if you have any additional questions, thank you!

Nicholas,

Thanks, that helps a lot!  Is there an example schematic or reference design for the PDN-3M?  I was given a PowerPoint that has part number call outs for the PDN-3M for the TDA4VL.  Also is the voltage supervisor required?  The part list I have calls for the TPS389004004, which doesn't seem to exist.
