Abstract:
A power supply circuit and a method for operating a power supply circuit involves selecting a normal operational mode or a pass-through operational mode for a switched mode power supply, in the normal operational mode, converting an input voltage of a power supply circuit to an intermediate voltage using a switching regulator of the switched mode power supply, in the pass-through operational mode, disabling the switching regulator such that the input voltage of the power supply circuit is unchanged by the switching regulator and an electric current consumption of the switching regulator approaches zero, and converting the intermediate voltage or the input voltage of the power supply circuit to an output voltage using a linear voltage regulator.
