Figure 23. Modes of Operation
It can be seen that in DCM, whenever the inductor runs dry the SW node will become high impedance. Ringing
will occur as a result of the LC tank circuit formed by the inductor and the parasitic capacitance at the SW node.

LINE REGULATION
The LM2696 regulates to the lowest point of the output voltage (VL in Figure 25 ). This is to say that the output
voltage may be represented by a waveform that is some average voltage with ripple. The LM2696 will regulate to
the trough of the ripple.
