Description
Pin Number
Name
Function
1 FB This pin receives a portion of the PFC output voltage for the regulation and the dynamic response enhancer (DRE) that speeds up the loop response when the output voltage drops below 95.5% of the regulation level.VFB is also the input signal for the Soft
Overvoltage Comparators as well as the Undervoltage (UVP) Comparator.
