Abstract: In accordance with a first aspect of the present disclosure, a power supply circuit is provided, comprising: a first output node and a second output node; an inductor detection unit configured to detect whether an inductor is present at the first output node and to output a corresponding detection signal; a mode control unit configured to control an operating mode of the power supply circuit in dependence on said detection signal; wherein the inductor detection unit is configured to detect whether said inductor is present by pulling down the first output node, deriving a reference voltage from the second output node, and comparing a voltage level of the first output node with said reference voltage. In accordance with a second aspect of the present disclosure, a corresponding method of operating a power supply circuit is conceived.
