AN1894 - APPLICATION NOTE

Following pictures starting from Figure 27 to Figure 34 show the most important voltage or current

waveforms at different input and output conditions. The channel 1 (pink) is the power MOSFET Source

terminal voltage of the VIPer12. The channel 4 (red) shows the inductor current. The purpose of those

pictures is to demonstrate the skipping cycle function at light or no-load condition and cycle-by-cycle

primary current limitation at overload or output shorted condition.
