ABSTRACT:
A dual mode external DC power supply system for supplying DC power to an electronic device and which operates under the control of the electronic device is provided. The disclosed embodiment of the power supply system includes a first input adapted to receive an input signal of unregulated DC power, a second input adapted to receive a control signal from the electronic device, and an output adapted to provide either a constant voltage DC output signal or a constant current DC output signal depending on the magnitude of the control signal. The control signal also determines the level of constant current delivered to the electronic device when the system is operating in the constant current mode. The disclosed embodiment of the DC power supply system includes a regulating circuit responsive for conditioning the input signal of unregulated DC power into a DC output signal, a voltage sensing circuit adapted to provide a first feedback signal to the regulating circuit, a current sensing circuit also adapted to provide a second feedback signal to the regulating circuit, and a switch responsive to the control signal, for operatively coupling the first feedback signal to the regulating circuit when the system is operating in the constant voltage mode and coupling the second feedback signal when the system is operating in the constant current mode.
