Abstract
In accordance with an embodiment, a method of driving a switching element in a switching converter includes generating a feedback signal that is dependent on the output voltage, driving the switching element in a plurality of subsequent burst cycles, determining a burst frequency, and adjusting an effective switching frequency in at least one burst cycle dependent on the determined burst frequency. Each burst cycle includes a burst-on period and a subsequent burst-off period, and determining the burst frequency includes evaluating a duration of at least one burst cycle.
