Abstract
Embodiments of devices, systems, and methods for controlling the output voltages and currents of a power converter as requested by an adaptive device are described. In one embodiment, a power converter includes a primary controller, a secondary controller, and an opto-coupler configured to communicate a communication request, including a load request, by a secondary controller to a primary controller in a feedback signal. A method may include the operations of: executing a request cycle, by extending an 'ON' state for a secondary switch, detecting a slope change in a scaled primary voltage signal, entering a communication-ready mode, converting a load request into communication information communicated in a feedback signal using an opto-coupler, decoding the communication information, and adjusting at least one of a reference voltage for output current and a reference voltage.
