PSPICE-FOR-TI: Simulation error with LM2743 model

Hey Mohamed,

Can you share your simulation file so that I can debug on my end?

Thanks,
Caleb

Hello Celeb,
LM2743_PSPICE_TRANS.rar

THANK YOU !

Hey Mohamed,

I've compared your model setup to the one that is available on the product page. Did you use the original model and then make edits to the circuit? I would take the model and make incremental changes until you figure out what is creating the error. Have you had the model work before?

Thanks,
Caleb

Hello Calbe,
Yes i've just edit the circuit from the Webench and it shows me the same error when I try to simulate both of monti-caarlo or worst cases.
Thank you

Hey Mohamed,

That means that there's something wrong with the setup of your circuit when you transferred over the design from WEBENCH to PSPICE. I would make incremental changes and run the simulation each time you make a change so you can isolate the source of the error.

Thanks,
Caleb

Hello Caleb,

As I mentioned earlier, the issue only arises when I'm attempting a Monte Carlo or worst-case simulation. I encountered the problem even when simulating the project directly from WEBENCH without any edits.

Thank you.
