We are trying to run transient simulations on a project using UCC2897
We saw no specific model is available for UCC2897, but we found models for UCC2891And unfortunately for UCC2891 the only transient model is for pspice and it's encrypted
here the questions:1) Is there a specific TINA transient model for UCC2897 (or at least UCC2891)? Also encrypted can be fine if Tina can manage encrypted models2) Is it possible to get a de-crypted version of transient model for UCC2897 (or at least UCC2891)?
Thanks in advance
Currently, we do not have a model for UCC2897. However, we are working on converting the UCC2891 PSPICE Transient model to TINA-TI. As soon as this is done, it will appear in the product folder. In the mean time, if you are interested in getting an unencrypted copy of the PSPICE model, please work with your local Field Applications Engineer and they can help you with this.

Thanks for the reply, we have just contacted our local FAE asking for the decrypted model
Best regards and thanks again
Even I was looking for a transient model of UCC2987/ UCC2891 on TINA TI. I am facing similar issues. Everything I find is encrypted. Did you manage to find anything? If yes could you please mail me the same. My email ID is - firstname.lastname@example.org.
Unfortunately no at the moment.
We are actually running average simulations to verify loop stability with TINA-TI model.
Only way to use encrypted models is to have PSpice SW with release later than 15.5 (if I'm not wrong...)Note that "Lite" version of the new 16.5 has a limit on nodes that you can simulate and the UCC2987 is exceeding this limit, so you can't use this evaluation version.
I'm sorry I couldn't help more
I wanted to simulate the active clamp forward converter (PTEA404120) using TINA TI. And UCC2897 is the controller used in it for PWM. Hence I cannot use the average model and I needed the transient model. Thanks a lot anyway.
Hi Alberto and Nikita,
Attached is the UCC2891 TINA-TI transient model. It will also be released to the product folder in a few days.
Thanks a lot. This would be of great help.
