Abstract
The invention pertains to a method for detecting and/or limiting short-circuit or overcurrent states of a switching regulator, where the load current or a variable proportional to the load current is measured and compared with a predetermined maximum value, and where the result of this comparison is used to influence the switching pulses. In this case, the result of the comparison between the load current and the maximum value is only taken into consideration within at least one time window during at least one timing period of the switching pulses.
