Guangyang,
The model is encrypted and will only run in the simulator in which it is encrypted (PSpice in this case).
You can request the unencrypted model but will need an NDA. What I can tell is that this model is pretty complex and may not work like other models by directly importing into TINA-TI without making significant tweaks. Please consider instead to use UCC28710 TINA-TI model which is already available:
Nikhil Gupta，
I download the Tina-ti model and run it in Tina, is there no transformer in that model(something like below), what am I suppose to do with that?
Thank you.
Guangyang,
I believe that the symbol is simply incorrect. However, if you right click on the symbol and select Enter Macro, you will see the following:
The transformer model is present and this shows the pinout for it. If you are having trouble running the simulation, I would recommend selecting the TINA default values for the simulation parameters (Analysis-->Simulation Parameters...). Click on the hand icon at the bottom right of the window and select TINA default. The simulation should take a while to run.
Guangyang,
After a test run, I have found that there is a quicker simulation if you change only 1 parameter from the downloaded reference design. Simply change the TR maximum time step from the 10G default value to 50n. This gives a better performance in speed and accuracy for the simulation.
Britt,
The design doesn't run for me after I changed the parameter you mentioned above. I don't have a specific transformer want to use. I don't know how to do No.4/5/6 in the below picture, I used to just choose DC Analyse for simulation, is there some thing wrong here.
Here is the simulation result I got, totally a mess.
