ABSTRACT:
A power supply provides a DC voltage to power an electronic device which includes battery charging circuitry. The power supply can be selectably coupled to alternative types of power sources and converts the power received from a power source to the DC voltage. The power supply includes source determination circuitry which generates a signal indicative of the type of power source to which the power supply is coupled. The DC voltage and the power source indication signal are provided to the electronic device. In response to the power source indication signal, a controller within the electronic device controls the amount of power drawn by the device by disabling the battery charging circuitry.
