Abstract
A method for controlling a load-current zero-crossing of a switching regulator having a high-side switch and a low-side switch includes detecting, by a spike detection circuit, a presence of a spike on an output voltage of the switching regulator, determining, by the spike detection circuit, in the event that a spike is present, whether the spike is a positive spike or a negative spike, and adjusting a turn-off timing of the low-side switch based on a determination result.
