Original question:

TPS53622: Simultaneous SVID and PMBUS operation

TPS53622: Using SVID interface alone

Part Number: TPS53622

In the datasheet, application information section provides SVID and PMbus together for Intel platform. Will it be OK to use SVID alone instead of both for Intel SOC? Are there any limitations if we dont use the PMBus interface along with SVID?

    Hi Anil,

    It is not a must to use PMBus, but even it is not used in the system, please reverse a connector for TI GUI in order to fine tune the loop and debugging purposes.

    After the project is MP, you don't need the connector afterwards.

    Thanks.

    In the datasheet, registers/data accessed by PMBus is provided. For SVID interface, there is no information on what all registers/data of TPS53622 can be accessed. As an example, I wanted to know if NVM contents can be accessed by SVID interface? Is there any document from TI that has this information? If not where can I find this info.

    SVID register is intel proprietary information so that the detail is not included in the datasheet. 

    You can refer to TPS53622 technical reference document for more information in terms of PMBus, if you want to get it, please contact your local TI representative.

    Thanks
