Test results and significant waveforms

In 
 
a startup tentative below the threshold is captured. As visible, at startup the 
RUN pin does not allow PFC startup.  
In 
 and 
 the waveforms of the circuit during operation of the brownout protection 
are captured. In both cases the mains voltage was increased or decreased slowly. As 
visible, both at turn-on or turn-off there are no bouncing or starting attempts by the PFC 
converter.
