I looked at the UCC28811 product folder and could only find excel design files for buck derived PFCs. This reference design is a single stage flyback for driving LED strings.
I did find the TPS92210 single stage PFC controller in a flyback for LED strings…
The circuit for the TPS92070 will be very different than the TPS92210 you have shown in your schematic. There is a design calculator for the TPS92210 (TPS92210_DESIGN_CALC ) that you could verify your design with.
I am presently having technical difficulties…
