Figure 29. This plot gathers waveforms captured at three different operating points:  
1st Upper Plot: Free run, valley switching operation, Pout = 26 W.  
2
nd Middle Plot: Min Toff clamps the switching frequency and selects  
the second valley.  
rd Lowest Plot: The skip slices the second valley pattern and will  
3
further expand the burst as Pout goes low.  
Vrsense (200 mV/div)  
Vgate (5 V/div)  
200 mA x Rskip  
Current Sense Pin (200 mV/pin)  
Figure 30. This picture explains how the 200 mA internal offset  
current creates the skip cycle level.
