A single wire serial communication method for a system having a master device and a plurality of slave devices sequentially connected by a single wire can include: in each communication, transmitting a data packet by the master device, and sequentially receiving the data packet by each of the slave devices; receiving the data packet and forwarding the data packet to a next slave device by a current slave device, where each of the plurality of slave devices when receiving the data packet serve as the current slave device; modifying device address data in the data packet by the current slave device; and comparing the device address data in the data packet received by the current slave device against a preset data or the device address data in the data packet transmitted by the master device, in order to find at least one target slave device in the communication.

Single wire serial communication method and single wire serial communication system

A control circuit for controlling a power converter can include: a constant voltage output module, a constant current output module, and a power stage circuit; and where the control circuit is configured to select one of a first feedback signal representative of output information of the constant current output module, and a second feedback signal representative of output information of the constant voltage output module as a feedback input signal based on operation states of the constant current output module and the constant voltage output module, in order to control a switching state of a power switch of the power stage circuit.
