TPS546B24A: .tifsp file Preperation for TPS546B24A

Part Number: TPS546B24A

Hi Team,

I have creatted Power excel sheet (TPS546x24A_Compensation_Pinstrap_Calculator_Release20200120) for regulator used in design.I want to create .tifsp file for it.

Is there any user guide how to prepare tifsp file based on Power sheet calculation so we can make sure that .tisf file generated correct.

In the TI fusion tool there are multiple option are available and really makes confuse what are the parameter we have to set from the excel sheet.

Many thnaks

    The PMBus commands that are set via pin programming are:

    COMPENSATION_CONFIG - If you are using pin programming, you can find the hex values for the switching frequency and compensation code setting in the Pin Programming tab of FUSION, and apply the selected setting  back to Frequency and Compensation.

    FREQUENCY_SWITCH

    TON_RISE

    IOUT_OC_FAULT_LIMIT and IOUT_OC_WARN_LIMIT

    STACK_CONFIG

    VOUT_SCALE_LOOP

    VOUT_COMMAND

    SLAVE_ADDRESS

    SYNC_CONFIG (for SYNC in or SYNC out)

    and INTERLEAVE (if using a single phase device)

    If you want the part to use the NVM programming and not the detected resistor programming, you will also want to update

    PIN_DETECT_OVERRIDE which controls whether values are loaded from NVM or from Pin Detection during power-on reset or RESTORE.

    Here is a video of a walk-through of the Digital Fusion Power Designer 

    https://www.ti.com/video/5740951388001 

    It doesn't specifically cover saying the system (tisfp) file, rather it covers configuring the part using the GUI software.   Once you have that, you can use the SAVE or EXPORT functions to create the system file.

    A system file is used to save multiple devices on the same bus to a single file.

    A project (XML) file is used to save a single device on the bus to a single file

    A programming script (CSV) file is used to save a sequence of programming commands used by a programmer to configure a part.
