AN3065 Test results and significant waveforms
Doc ID 16279 Rev 2 19/33
In Figure 24 a startup tentative below the threshold is captured. As visible at startup the
RUN pin does not allow PFC startup.
In Figure 25 and 26 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.
