Abstract
In one embodiment, a power adapter comprises a power supply to output power for powering a powered device. The power adapter outputs information indicative of an amount of power output by the power supply for use by the powered device to control the amount of power used by the powered device.
Claims19
A power adapter comprising:
- a power supply to output power for powering an electronic device;
- wherein the power adapter outputs control information when the electronic device should reduce an amount of power used thereby, the control information for use by the electronic device to control the amount of power used by the electronic device;
- wherein the power adapter outputs the control information when the amount of power output by the power adapter exceeds a value;
- and
- wherein the control information comprises information indicative of by how much a load current output by the power supply exceeds the value.
2 more elements
A computer system comprising:
- a computer;
- a power adapter that is separate from the computer;
- an interface to receive power from the power adapter;
- wherein the computer receives control information output by the power adapter when the computer should reduce an amount of power used thereby;
- wherein the power adapter outputs the control information when the amount of power output by the power adapter exceeds a value;
- wherein the computer uses the control information to control the amount of power used by the computer;
- and
- wherein the control information comprises information indicative of by how much a load current output by the power adapter exceeds the power output value.
5 more elements
A device comprising:
- an interface to receive power from a power adapter;
- wherein the device receives control information output by the power adapter when the device should reduce an amount of power used thereby;
- wherein the power adapter outputs the control information when the amount of power output by the power adapter exceeds a value;
- wherein the device uses the control information to control the amount of power used by the device;
- wherein the control information comprises a control signal that is generated when a load current output by the power adapter exceeds a throttle current value;
- and
- wherein the control information comprises information indicative of by how much a load current output by the power adapter exceeds the throttle current value.
4 more elements
An intermediary device comprising:
- an adapter interface to couple the intermediary device to a power adapter in order to receive power from the power adapter;
- and
- at least one device interface to couple the intermediary device to an electronic device;
- wherein at least a portion of the power received from the power adapter is applied to the electronic device;
- wherein the intermediary device receives first control information that is output by the power adapter when the amount of power output by the power adapter exceeds a value;
- wherein the intermediary device communicates to the electronic device second control information, wherein the second control information is used by the electronic device to control the amount of power used by the electronic device;
- and
- wherein the second control information is derived from the first control information.
