Universal Power Adapter
First Claim
1. A power adapter device comprising:
- at least one terminal at which the power adapter device receives first input power having a first input power characteristic, and provides first output power having a first output power characteristic;
a conversion device coupled to the at least one terminal, wherein the conversion device is capable of converting at least a portion of the first input power having the first input power characteristic into at least a portion of the first output power having the first output power characteristic; and
a processing device coupled to the conversion device, wherein the processing device controls the conversion device based upon at least one informational signal received from an external location.

Abstract
A power adapter device and a power delivery system are disclosed herein. The power adapter device includes an input terminal at which the device receives input power having an input power characteristic, and an output terminal at which the device provides output power having an output power characteristic, where the device is further able to receive an informational signal via the output terminal. Additionally the power adapter device includes a conversion device coupled between the input terminal and the output terminal that is capable of converting at least a portion of the input power having the input power characteristic into the output power having the output power characteristic, and a processing device coupled to the conversion device, where the processing device controls the conversion device based at least in part upon the informational signal so that the output characteristic of the output power satisfies a requirement specified by the signal.
