WEBENCH® Tools/TPS54620: Unable to find bode plot / phase margin analysis tool or graph

Part Number: TPS54620

Tool/software: WEBENCH® Design Tools

attempting to modify an existing TPS54620 to add remote sense, and use WEBENCH Designer for the first time. I can get the voltage waveform, but can't figure out how to do a stability analysis.  The only icons I have are: NEW, EDIT, BOM, SIM, EXPORT, SIM EXPORT, SHARE DESIGN HELP.  Selecting "SIM" doesn't bring up any additional menus.

  • Mark,

    Under Sim, you should see Bode Plot Sim option. Also check out Re-Comp button.

    No its doesn't appear once you edit the schematic and add a cap. As I mentioned previously, once you start editing the schematic, you can't get back to the screen that shows these other options.
  • In reply to Mark Wagner48:

    Yes, once you use free form edit, there is no way for us to know what circuit it is so Bode plot average models are not supported after that. For such cases, please use the TINA-TI average model on the web instead. There is a reference design example which you can use as a starting point and start modifying from there.
