    Hi Maharajan, 

    Thank you for reaching out on E2E!  I believe I have just answered some of your questions in another thread, but let me also answer here for clarity. 

    1. BUCK and LDO settings can be configured using the TPS65219_GUI tool. This is used for both the TPS65219x and TPS65220x family. 

    Settings can be configured directly in the respective register or by using the Power Resources section in the Configuration-NVM Fields tab:

    2. Yes. After configuring settings using I2C, the steps for "NVM Programming" can be followed to overwrite the desired settings to the device, to make your settings the new default value upon power up. 

    3. The TPS65219EVM-SKT (5x5) can be used to program the TPS6522005-EP chip before installing onto your board, with the TPS65219_GUI mentioned earlier.
    Settings can be configured directly in the respective registers or by using the Power Sequence sections in the Configuration-NVM Fields tab:

    The TPS65219 NVM Programming Guide provides details on this process, which is the same for TPS65219x and TPS65220x devices

    Let me know if you have any additional questions on this process.

    Best Regards, 
    Sarah
