Simuliation problem with TLV8812

Part Number: TLV8811
Other Parts Discussed in Thread: TLV8812

Hello all.
I am having a problem with the simulation of TLV8812 in PSpice for Ti. In Pspice for Ti, I don't find the TLV8812 spice model. Therefore, I add the model From the Texas Instruments website, and I have problems with simulation because the Pspice shows many errors. If I solve one of the errors, it appears a new error. List of errors:
Error(ORPSIM-15661)
ERROR(ORPSIM-15138): Convergence problem in Transient Analysis at Time = 227.0E-12. Time step = 784.8E-21, minimum allowable step size = 1.000E-18. It is the first error.
I really appreciate any help you can provide.

Hi Tomas,

Please take a look at the following thread. You may require to import the model into PSpice for TI.

Hi Raymond,

Thanks for your answer.

I am have imported this model, as shown on this thread

https://e2e.ti.com/support/amplifiers-group/amplifiers/f/amplifiers-forum/932546/tlv8812-about-pspice-model?tisearch=e2e-sitesearch&keymatch=TLV8812#

but this does not solve the problem. Pspice shows the same errors that before.

Hi Tomas,

I assumed that the model issue is resolved. If you have additional questions, you may still reopen the thread or create a new one via E2E forum.
