Is PFC needed in TOP261 228W design?
I`m student developer who really uses your product.
While using TOP261, I have some questions.
One of my processor says PFC parts must be included in my design when I make my product if my product exceeds 100W and input voltage is 85~265VAC.
And while PI Experience, I found suggested design doesn`t include PFC at all.
(And there are no TOP261 in universial voltage input)
so I have a confusion. I used AL6562A as my PFC, Am I doing it right?
