UCC28730: USS28730

Part Number: UCC28730

I used  Workbench to get a design with UCC28730.

Pl see attached sch.

The vout values used is 12V

But the results say " actual vout is 18V"

I am wondering if this is not a typo: most likely, Vout_aux for primary side control might be 18V

Cld you look into this pl?
