    Hi Lucia,

    This PMIC are using for TL10(Marvell), pls check the attached file for the design details, as you know, the default vref=0.8V, we want keep the vref=0.8V for SW1, SW2, SW4, and change VFB3 vref to 0.7V.

      Base on the design, could you help generate the programming files to us

    Thanks

    Hi Rick,

    We don’t have an example code. But if you have any questions to setup the I2C registers, we would like to help.
    I will work on the I2C register setup guideline and I will try to share you before end of tomorrow. Thanks!

    Hi Rich,

    Please find below guidance about how to set Vref for each rail:

    The page command provides the ability to configure and monitor multiple outputs on a single TPS65400.

    The Vref_command sets the voltage reference for the selected output.

    Thanks!

    Hi Lucia,

    About TPS65400 programming, we learned that "In order to streamline the programming of the TPS65400 in a production environment, these .xml
    formats can be converted into a .hex format.".

    But we don't have a detailed procedure. What tools should we use to complete the conversion of file formats? Can you provide any document or recommendation ?

    Thanks.

    Max

    Hi Max,

    We have two guidance about how to program. Pls kindly check whether it will be helpful. For the different format convert, I am afraid that's not what you usually support.

    Hi Max,

    Could you pls send me your xml file first? Let me try to convert it to .hex and send back to you to see whether it can work.
