Abstract
The present disclosure describes a power supply with multiple operating modes, to detect a load condition of an electronic device, and to automatically change between the multiple operating modes to supply an output direct current (DC) signal to the electronic device based on the load condition detected by the load detection mechanism. The power supply includes multiple control topologies that are each associated with one of the operating modes. Changing from a first operation mode to a second operation mode includes changing from a first control topology associated with the first operation mode to a second control topology associated with the second operating mode to supply the output DC signal at a predetermined voltage level.
