Designer WEBENCH

Other Parts Discussed in Thread: TPS43060, TPS92640

Dear Designers, TI Support.

1) I'm using the TI WEBENCH to design a step-up power supply with the TPS43060. I want to change a device from the proposed ones  in the BOM generated by the WEBENCH. I can, of course, change 1 device at time, but if a change a second device, the first one (the one I previously changed) is automatically updated and changed by the BEBENCH.  How can I stop the automatically update of the BOM by the WEBENCH to freeze it and change any device I want ?

2) WEBENCH proposes a PCB with copper area predefined to dissipate the heat in the thermal design. If I tray to cancel all copper area in 1 intermediate layer, automatically all the copper areas in the other layers are cancel. How can I avoid it ?

3) Is it possible to import the Gerber file of my PCB for the thermal simulation ?

4) I want to use the WEBENCH to design a step-down converted based on TPS92640 device, but I don't see it in the device list. Is it possible to design a converter using the TPS92640 ? How ?

Thanks and Regards,

Paolo

    Hi Paolo,
    You should be able to change multiple individual components without any problem in WEBENCH. You will go back to your original design, only if you change the design inputs or click on the Update button on the Advanced User inputs on the left side. Probably try using a different browser such as Chrome.

    We will get back to you on question 2.

    Regarding question 3, we currently do not support importing Gerbers into the tool for thermal simulation. You can however, modify the PCB layout to your needs and run the sim (looks like this is what your question 2 is about).

    The integration of TPS92640 into WEBENCH is currently in work and we will let you know once it becomes available.

    Regards,
    Gerold

    Paolo,

      To follow up on Gerold's reply, can you send any more details about how you are changing the BOM components?  Are you going to the BOM page and using the Select Alternate Part button or are you clicking on a component in the schematic and then clicking on the Select Alternate Component in the pop up window?  After you get into the Alternate Parts page are you clicking on the Select button next to the desired component?  Are you using the optimization dial or any of the Advanced Options in the leftmost panel? 

      Also, there is a video which gives more details about the alternate part selection on the WEBENCH training video page.  It is video number 4 in the list on the page below:

    Dear HJeff

    To follow up on Gerold's reply, can you send any more details about how you are changing the BOM components?  Are you going to the BOM page and using the Select Alternate Part button

    YES even with Chrome

    or are you clicking on a component in the schematic and then clicking on the Select Alternate Component in the pop up window?  

    YES Even in this way. No differences, same problem

    After you get into the Alternate Parts page are you clicking on the Select button next to the desired component?

    If you click in the "Alternate Parts" button in the  BOM window you co in the Alternate Parts page

    Are you using the optimization dial or any of the Advanced Options in the leftmost panel?

    Yes and this is the problem, I think, is the optimizer that change automatically the devices. How can I disable the Optimizer ?

    Paolo,

      Would you be available to do an on line WebEx so we can look at the details?  If so, can you send me an email at jeff.perry@ti.com and I will set this up?

    Regards,

    Jeff
