A switched mode power supply includes an input for receiving an input signal voltage, a flyback converter circuit arrangement and an output for delivering a regulated output signal voltage. The switched mode power supply further includes a boost converter arranged to be operatively combined with the flyback converter, and functioning such that the combined converter operates in a boost mode when the input voltage is above a threshold value, and in a flyback mode when the input voltage is below the threshold value.
