Abstract
A switching power supply includes a secondary control circuit coupled to a secondary side of a transformer of the switching power supply, and a primary control circuit coupled to a primary side of the transformer. The secondary control circuit is configured to receive a power request signal of a load device, and encode the power request signal to generate encoded information. The primary control circuit is configured to receive, by use of the transformer, a feedback signal reflecting an output voltage of the switching power supply, decode the encoded information based on a change of the feedback signal, and based thereon, control the switching power supply to supply power to the load device.
