Abstract
A method of operating an electronic converter is provided in which a switching activity of a switching stage of the electronic converter is active or inactive based on a control signal, and the method includes operating the electronic converter, alternatively, in a first or a second mode. In the first mode, the status signal is initially asserted and is de-asserted in response to an amplitude of the input sensing signal failing to reach a first reference threshold value. In the second mode, the status signal is initially de-asserted and an auxiliary power supply signal is periodically varied with a variation period. After a time interval equal to the variation period, a comparison signal is asserted in response to an amplitude of the sensed signal reaching a second reference threshold value. The status signal is asserted based on conditions of the comparison signal and the periodically varying auxiliary power supply signal.
