Abstract
A multiphase switching converter has a plurality of switching circuits coupled in parallel, and a plurality of control circuits configured in a daisy chain. Each control circuit receives a phase input signal, and provides a phase output signal and a switching control signal for controlling a corresponding switching circuit. One of the control circuits is a master control circuit, if a fault is detected by the master control circuit, then the master control circuit provides the phase output signal satisfying a master transfer type, and then the master control circuit changes to a slave control circuit.
