Tool/software: WEBENCH® Design Tools
Trying to design a 600W PFC unit using the UCC28063A I used the WEBENCH tool.
For the L1 and L2 the suggested NstoNp is 7.413m. Does this means that Np/Ns = 1/0.007413=135?
From the datasheet eq 22 it is shown Np/Ns = 8. Also the same is given with the excel calculation tool.
Could somebody give a clarification?
