I think I have to correct this statement
from the worksheet, capacitor requirements are not determined by the PFC frequency, please check this formula (pic) below
*for the same power, the higher the output voltage the smaller the capacitor needs
I thought the PFC frequency determined the size of the capacitor, I was wrongSorry Silvio,
With the presence of PFC, capacitor requirements can be smaller, I attach an excel file for PFC calculations (I downloaded from onsemi website) in post # 5
