The present invention provides a power supply circuit for driving multiple sets of DC loads. The power supply circuit includes a current providing circuit, a sharing circuit and a current control unit. The current providing circuit receives and regulates a supply voltage into specified output currents to be supplied to the multiple sets of DC loads. The sharing circuit is connected in series with output terminals of the current providing circuit and the multiple sets of DC loads. The sharing circuit includes at least one coupling inductor member for performing equal current sharing among the multiple sets of DC loads. The current control unit is connected to the current providing circuit and the multiple sets of DC loads for detecting magnitudes of the current passing through the multiple sets of DC loads and controlling the output currents from the current providing circuit.
