Hi Greeshma,

Thanks for reaching out to us.

Could you tell me which file you are referring to?

I tried to run the TINA simulation file located at https://www.ti.com/lit/tsc/slum277 . I didn't find any issues.

Hi,

Thanks for the reply. Can u please check on the attached model and help me resolve the issue

Hi,

Looks like you have attached only the controller model. I don't see any power stage circuit in your model.

Do you have a reference model for the boost operation using, UCC28950

Sorry we do not. You should be able to modify the transformer turns ratio to get the design to boost.
