Abstract
The present disclosure provides a multiphase switching converter and control circuit thereof. The multiphase switching converter includes a plurality of control circuits forming a daisy chain architecture, and to generate a preparatory output signal and a switching control signal for controlling a corresponding switching circuit when receiving a clock signal from a communication bus in the preparatory state, the control circuit is configured to operate in a preparatory state when receiving a preparatory input signal. Only preparatory signals are transmitted between the plurality of control circuits, and a signal for controlling circuit being on is participated by the clock signal generated by a host controller, so that the host controller does not need to track a position of a current unit in real time during a control process of all units, thus greatly simplifying a design of the host controller and reducing a circuit cost.
