Abstract
A sequence assignment method used in multiphase switching converters with daisy chain configuration, wherein the multiphase switching converter includes a plurality of switching circuits coupled in parallel, and a plurality of control circuits configured in a daisy chain and sharing a phase control signal. Each control circuit generates a phase output signal, and a switch control signal for controlling a corresponding switching circuit based on a phase input signal and the phase control signal. The sequence assignment method includes: configuring one of the control circuits as a master control circuit to provide the phase control signal, wherein the phase control signal has a plurality of pulses for successively triggering the plurality of switching circuits to provide power to a load; respectively configuring the rest of the control circuits as a slave control circuit to receive the phase control signal; modulating the plurality of pulses in the phase control signal, through the master control circuit, to respectively generate a sequence information for each slave control circuit; and obtaining the sequence information, through each of the slave control circuits, based on the received phase input signal and the phase control signal.
