Abstract
A power adapter for supplying electrical power to a device includes a processor, an interface for power transfer with the device, a multi-winding feedback converter to receive an AC power input and to convert the AC power input to a DC power output over the interface for the device, and a power conversion control circuit. A voltage level of the DC power output is set based on a reference voltage produced by the processor. The power conversion control circuit receives the reference voltage and a control signal based on the voltage level of the DC power output to generate switch control signals to control switches of the multi-winding feedback converter to control the voltage level of the DC power output. The processor recognizes a load associated with the device and sets, using the reference voltage, the DC power output based on the recognized load.
