Abstract
The invention concerns a method and device for controlling the switching operation in a switch mode power supply module. The switch mode power supply module is intended to supply power to an item of equipment. The method comprises the steps of measuring, in the switch mode power supply module, the load current and comparing the measured load current with a predefined load current threshold value, and, cyclically interrupting the switching operation if the measured load current inside the device is less than the predefined load current threshold value.
