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.

Thanks

Guru
