Zusammenfassung:	A controller for a power converter. The power converter comprises a converter-switch and a converter-inductor. The controller comprises a controller-output-terminal configured to provide a switch-control-signal for the converter-switch, a comparator and a delay-block. The comparator can provide a comparator-output-signal that has a comparator-output-state dependent on whether or not a sensed-signal is greater than a reference-signal, wherein the comparator-output-state can take a first-state-value or a second-state-value. The delay-block can: set a time-delay-value based on: (i) a voltage across the converter-inductor; start a timer when the comparator-output-state changes; and cause a change in the switch-control-signal when the timer reaches the time-delay-value.
