Hello @andypark
Thanks for providing the requirements.
PFC stage you can use this reference document for your calculations.
Buck converter stage you can use this reference document.
Both documents have the formulas so please calculate as per your requirement.
Both converters will help for your entire project design.

Hello @andypark
Please provide us with complete requirements to us. which topology do you need it Isolated or nonisolated?
The reference design which you attached is isolated topology. In fact, Infineon has an isolation topology kindly click here.
Infineon don't have application board for non isolated topology.
