I found this link on the e2e that may help.
I checked the files you sent and the model seems to be different (like this) :
Unencrypted Model (you shared above):
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,
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
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,
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.
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.
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.
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.
