I found this link on the e2e that may help.

Hello Mike,
I checked that link earlier, but the mail bounced back which is why I posted here.

Hello Mike,
I checked the files you sent and the model seems to be different (like this) :
Unencrypted Model (you shared above):
Encrypted Model:
It does not look like the available encrypted model of UCC28951-Q1 (which is also discussed earlier in this thread: https://e2e.ti.com/support/power-management-group/power-management/f/power-management-forum/923395/ucc28951-q1-ucc28951-q1-unencrypted-pspice-model? )
Can you please send the Unencrypted Pspice model with all the pins?
Thanks & Regards,
Hi Mike,
We are checking the unencrypted model you sent in Pspice(first picture of my previous reply) so there is no import problem. (we have not yet imported it)
Be it an unencrypted or an encrypted model, it should have the same functionality and ports. But the model you provided is different than the model available on UCC28950/51
https://www.ti.com/lit/zip/slum169
So our conclusion is the unencrypted model you provided is totally different from the encrypted model available on UCC28950/51 page.
I am looking for the unencrypted version of the following transient PSpice model.
Thanks & Regards,
Hello,
I download the following unencrypted file from the repository. Give this a try to see if it works any better?
ucc28951-q1-master@6c2cd959c12 (1).zip
Regards,
Hello Mike,
Thanks for sending these files,
But looks like it only has the unencrypted files for the Average model, whereas the following encrypted model: https://www.ti.com/product/UCC28950#design-development is a transient model.
You can see the difference below: the number of pins is less for the unencrypted Avg model(top) than the Transient encrypted model(bottom)
We are looking for unencrypted transient model.

Hello,
If you are just looking for the model of the controller, I would think this should be fine. If not let me know and I will see if I can get the unencrypted model for the transient model. The controller should be the same for both models.

Hello Mike,
Yes, we want the unencrypted model for the transient model of UCC28950 controller.
Thanks in advance,
Hello,
I searched the repository and the only model that is available unencrypted model that is available is the transient.
The model developer had used this model of the IC in the average model and therefore did not save the entire model unencrypted.
You should be able to use the unencrypted model of the IC to import into your software tool.

Hello Mike,
I am a little confused with what you said, maybe i am not able to make my point clear:
- As mentioned in my previous reply the number of pins & name of the unencrypted model is not matching the number of pins of the controller in the datasheet and encrypted model.
- It looks like the unencrypted file you sent is for the average model.
- We are looking for an unencrypted transient model exactly like the encrypted transient model of the controller to use in AMS.
