Hi, I am trying to simulate a PFC Boost converter using UCC28180 controller and I am using LTspice. I added the unencrypted model of it in my LTspice library but when i try to simulate the circuit i create, an error message pops up saying "Syntax error-- Unknown Symbol: Vin". I'm not familiar with the codes used in spice model so i am out of ideas on how i will fix this error and simulate it on either LTspice . Please help me in this matter and i want to know why this error occurs. Thanks.

Hi Subhajit

The UCC28180 models are average models and not time domain transient models. The models are for use in the TI TINA simulator which is free to download.

I suspect the model will not work in LTSPICE and unfortunately we cannot support LTSPICE as it belongs to another company.

The TI TINA simulator can be downloaded from here,

Regards

Peter
