In Discontinuous mode, when the inductor current drops to 0 A, the voltage at the SW pin rings, due to the capacitance in the resonant LC circuit formed by the inductor and the capacitance ofthe switch and the diode. This ringing is low-frequency and is not harmful. It can be damped with a resistor across the inductor, but this reduces efficiency and is not recommended.
