PFC-FB (cont.)
The actual input voltage to the PFC-FB pin is the step-up voltage divided with a resistance (see figure below).
If R1 is set as 710 k
W
and R2 as 4.7 k
W
, the decision voltage at the step-up pin (+B) is as shown in the figure below.
All numeric values in the figure are typical values.
