OFFLINE FLYBACK REGULATOR
SLOPE COMPENSATION
A fraction of the oscillator ramp can be resistively
summed with the current sense signal to provide slope
compensation for converters requiring duty cycles over
50%.
Note that capacitor, C forms a filter with R2 to suppress
the leading edge switch spikes.
