  • Hello all;

    I have not been able to see any way to add some 'real world' parasitics to the schematics that are generated... for instance, TPS62085, I wanted to add a small resistance and inductance between VOS and the output capacitor, to simulate the effects of a 'bad' layout, and there does not seem to be any way to accomplish that, for any of the connections? ?

  • Further to my previous question/issue about being able to 'freely' modify schematics, I wanted to check the behaviour of this TPS62085 with VOS connected poorly, or, indeed, see what happens if VOS is NOT connected to the output, floating... I like to be able to simulate possible fault conditions, as well as 'normal' operation, since I expect that the fine AEs at TI have already beat to death the 'normal' operation of these parts ;-)

    Barry,

    You can use the export to TINA-TI option to modify the schematic and simulate the response.

    That's just dandy, if one has TINA-TI ;-)

    My corporate IT will not allow 'unauthorised programs' in the house...

  • In reply to Barry Rowland:

    Barry,

    You can try either of the following alternative options in that case:

    1. Cadence OrCAD export option and simulate using Cadence SPB 16.6 or higher.
    2. Altium Designer export option and simulate using Altium Designer.

    The detailed instructions on installation and usage for each of these options can be found in the downloaded zip file once you finish the export. Hope this helps.

    Regards,
    Amod
  • In reply to Amod Vaze:

    Thanks, Amod;  I have neither option, myself, but will check with colleagues who may have a licence, or a floating licence.

    It would certainly be much nicer if the 'easy, breezy' Webench would allow a bit wider range of experimentation, but...

    Best regards from Austria

    Barry,

    Hope you got hold of a license so you could try exporting and simulating the design. Thanks for all the feedback - I will convey it to the team so we can further enhance the tool.

    Amod

  • Hello Kaitlin,

    I couldn't found thermal analyzer in new version of WEBENCH.
    Has the thermal analyzing function been removed?
  • In reply to Miao Gu:

    Miao,

    We are currently not supporting thermal simulations in the new HTML5 WEBENCH Power Designer tool. We’re actively developing features that will help you estimate junction temperatures based on your design configuration, and can notify you as soon as the feature is released.

    Regards,

    Amod

  • Yes, right.

    But, I try a simple design : AC-DC power supply 85-250VAC to 5VDC/0.5A not isolated.

    A lot of answers but nothing "not isolated" and it's like this option have no effect for the design.

    So have you really a not isolated design to make a very low cost power supply ?

    Regards.
