Evaluation Board for 80W PFC Supply 

 

 
The  figure  shows  the  input  voltage  (230V~)  in  orange  color,  the  current  (I

out

=0.20A)  in  blue  color  and 

the  ripple  of  the  output  voltage  in  green  color  (only AC,  C13=47µ,  C6=0.1µ). The  ripple  is  lower  than 
20V peak-to-peak (<5%).
