Other Parts Discussed in Thread: UCC27201,
The UCC27201_TRANS.LIB SPICE model downloaded from TI's website has several typos.
In 2 places: "1.1.75" should be "1.75"
Here's a link to the model:

I downloaded it from the UCC27201A product page: http://www.ti.com/product/UCC27201A?keyMatch=ucc27201adda&tisearch=Search-EN-Everything
Hope this helps!
