TINA/Spice/UCC27201: UCC27201 Unencrypted Model Issue

Richard,

It appears that the .lib file has been corrupted in some way, either by 17.2 or by the download. Here is what those lines look like in the actual unencrypted PSpice model:

E_U5_E1         U5_THRISE VSS TABLE { V(VDD, VSS) }
+ ( (8,1.45)(10,1.55)(12,1.65)(14,1.1.75)(16,1.80)(18,1.90)(20,1.95) )

and

E_U1_E1         U1_THRISE VSS TABLE { V(VDD, VSS) }
+ ( (8,1.45)(10,1.55)(12,1.65)(14,1.1.75)(16,1.80)(18,1.90)(20,1.95) )

I would have the user download the file again (or use the one I have attached below) and see if that corrects the problem.

UCC27201_TRANS.LIB

Britt,

Thanks for your quick response!

Thanks again.

Britt,

Can you look at the model that you attached to the previous response and make sure that it is the correct one?

The customer stated that he is still seeing the issue.

Thanks for your help with this!

Britt,

Have you had a chance to look at the last question I posted?

Thanks for your help with this!

Britt,

Can you verify that the model that you attached is correct?

The customer still see the same error.

I just want to make sure that we have sent him the proper model.

Thanks for your help with this!

Hi Richard,

I used the unencrypted model , downloaded off of the WEB and ran the simulation in 16.2 and it worked fine. I also ran the simulation in 17.2 and it worked fine.

So the model by itself has no problem running in either versions of  PSPICE. If you want you can send me their project folder and  I can try it on my end and see  if I can find what causes  the issue in their set up, but the un-encrypted model is fine and works in both 16.2 & 17.2 without any issue.

Kind Regards,

Arash
