I was wondering if it is possible to get a copy of the unencrypted Pspice lib file for the UCC28951 or UCC28950.

Thank you

Hello,

I searched the e2e and found this link that will bring you to the unencrypted PSpice model for the UCC28950/1 devices.

This encrypted model is missing pins and is the average model. Do you guys have the unencrypted transient model?

Thank you

Hello,

I found this link to an UCC28950 unencrypted model. The devices parametrically are the same and the pin out is the same. Hopefully you can use this model in your evalation.

Hello,

I found the attached unencrypted file that seems to have the full pin out and have attached it for your reference.
