Part Number: TPS62840-1DLCEVM55

Hi,

I have downloaded the SLVMD75 and SLUM691A file from TI website. I am able to run it on OrCAD Pspice.

I am getting following issue while running in temperature Sweep mode. "ERROR(ORPSIM-16550): Floating point computation failed during matrix solution. Possible solutions: 1)Ensure that all device parameters are in valid range. 2)Try using .options LIMIT INTERNAL ERROR -- Overflow, Multiply"

Do you have any idea why this issue is there in temperature Sweep mode?

Please find the attached file for more information.

I want to see the circuit behavior at -40 -20 0 25 50 and 70 degree C.

Best Regards,

Rahul

  • Hi Rahul,

    I could not find any attachments. In any case, I will check the simulation files and get back to you in 2 days.

    Hi Rahul,

    Unfortunately, our pspice models do not integrate temperature measurements and that is the reason you get this error message.

    Please reach out to us for any further support in the future.

    Then how can I simulate for the temperature variation?

  • In reply to Rahul Bhagat2:

    Hi Rahul,

    TI pspice models are not integrated with temperature sweep measurements. So you will need to use dedicated thermal simulators for this. We did have thermal models in the past but currently we do not have them.

    Can I get more information about what exactly you want to analyze? For instance, our Webench tool can be used to set different temperatures and all the electrical parameters will be computed. But of course you can't do a temperature sweep from t1 to t2.

    Hi Rahul,

    Do you have some updates to share? I did not hear from you.

    Hi Rahul,

    I hope my explanation helped you in understanding our pspice models. May be for thermal simulations you can use a dedicated tool. If there is something else we can help you with, please feel free to reach out to us. For now, I would like to close this thread.
