Beschreibung
Zusammenfassung:	A burst-mode controller for a DC-DC converter, the controller comprising: an output module configured to provide a switch control signal to the DC-DC converter, the switch control signal comprising a plurality of burst windows, each burst window corresponding to a period of a fixed-frequency burst clock and comprising a number of switching cycles; an on-time-control-module configured to: receive a compensation signal, wherein the compensation signal is based on the output voltage of the DC-DC converter; and set an on-time of the switching cycles of the switch control signal based on the compensation signal; and a burst-control-module configured to regulate the on-time of the switching cycles of the switch control signal by setting the number of switching cycles for each burst window of the switch control signal.
