Functional Description
2.4.5 Optional THD Correction dedicated for DCM Operation
For applications with a wide input voltage range and / or for applications using a wide variation of the
power e.g. dimming, the application might work in the DCM (Discontinuous Conduction Mode). In
order to minimize the high order harmonics during DCM, the detection of the DCM should be as close
as possible at the point of inflection of the PFC drain source voltage shown in Figure 18.
Figure 18 Signal Shapes with optional damping of oscillations during DCM operation of PFC.
This can be realized with an optional damping network (R4, D10 and Q4 see Figure 19) from the AUX
pin to the ZCD resistor R13.
