This will cause unnecessary power consumption in those electronic devices, which will reduce the power output from the adapter to a certain extent
[0006] In addition, since the voltage level of power output by the adapter may differ depending on the kind of electronic equipment used with the adapter involved, it is practically difficult to use the adapter in various electronic equipment
[0007] Also, it is possible that an unsuitable adapter used on an electronic device by an ordinary user who may not have sufficient knowledge of the electronic device or the adapter, for example using an adapter for a laptop computer on a monitor, may damage the electronic device

An electronic device includes a system unit having a plurality of electronic components; a system power supply supplying power to the system unit; a system power controller managing the power supplied from the system power supply to the system unit; and an adaptor including an AC / DC converter converting AC power inputted thereto into DC power corresponding to a selected voltage level amongst a plurality of voltage levels outputted therefrom and outputting the DC power corresponding to the selected voltage level, and an adaptor controller controlling the AC / DC converter to output the DC power corresponding to the selected voltage level amongst the plurality of voltage levels to the system power supply, based on a level selection signal supplied from the system power controller. Thus, the present invention provides an electronic device having an adaptor which can selectively output power according to a level selection signal supplied from the electronic device, and the adaptor used therewith.
Description
Technical field [0001] One aspect of the present invention relates to an electronic device, and in particular to an electronic device having an adapter and an adapter used with the same, wherein the adapter can selectively output in multiples according to a level selection signal provided from the electronic device. One of two voltages. Background technique [0002] Recently, electronic devices such as laptop computers, notebook computers, personal digital assistants (PDAs), mobile phones, CD players, and video cameras that use batteries have been widely used because they are portable. These electronic devices include adapter connection terminals in order to use an adapter for converting commercial alternating current (AC) power into direct current (DC) power. [0003] In addition to the adapter, the portable electronic device can also use power from a battery, so that the device can be used without connecting the adapter to an AC power outlet. On the other hand, when the adapter...
