Abstract: In some embodiments, a system may include at least one voltage controller. At least one of the voltage controllers may assess, during use, an occurrence of a predetermined condition. In some embodiments, the system may include an at least first capacitor. The at least first capacitor may be coupled to at least one of the voltage controllers such that at least one of the voltage controllers engages the at least first capacitor to supply additional current when the predetermined condition occurs. When the increase in current is no longer required the at least first capacitor may be disengaged. The at least first capacitor may be charged when disengaged until a predetermined capacity.

Abstract: Circuits, methods, and apparatus that may allow an electronic device to control a power adapter. One example may provide an electronic system where an electronic device may control a power adapter through a communication channel. Data transferred in the communication channel may include the temperature of the power adapter, the charging capability of the adapter, and other types of data. In one example, power and data may share the same two wires, and the power and data may be time-division multiplexed. That is, the two wires may convey power and data at different times. Another example may include circuitry to detect a connection between the electronic device and the power adapter. Once a connection is detected, power may be transferred from the power adapter to the electronic device. This power transfer may be interrupted on occasion to transfer data between the power adapter to the electronic device.
