Abstract
A switched mode power supply includes a switching device, the switched mode power supply being operable to convert an input voltage (V) to an output voltage (V) by switching the switching device, and a voltage regulator operable to generate a feedback signal based on at least one of the output voltage and an output current of the switched mode power supply. The power supply further comprises an overload detector, which is arranged to receive the feedback signal and operable to determine whether the feedback signal is outside a predetermined range. If the feedback signal is outside the predetermined range, the overload detector is operable to determine that the switched mode power supply is in an overload state, and when an overload state is determined, perform control to place the switched mode power supply in a non-operational state.
