Claim 32:
33. A control method configured to operably control a scalable multi-phase switching converter, wherein the scalable multi-phase switching converter includes: a plurality of converter modules, which are correspondingly coupled to a plurality of inductors so as to operably convert an input voltage to an output voltage by alternating multi-phase switching; the control method comprising:
in a setting mode, receiving a setting signal from a setting pin and determining an operation mode and a phase serial order according to the setting signal;
in master operation mode, generating a basic trigger pulse according to a feedback signal and generating a multi-phase trigger pulse signal at a trigger pin according to the basic trigger pulse;
in slave operation mode, receiving the multi-phase trigger pulse signal at the trigger pin;
generating an ON-trigger pulse according to the multi-phase trigger pulse signal and the phase serial order; and
generating a conduction control pulse according to the ON-trigger pulse, so as to control the plurality of inductors to generate the output voltage.
