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.

Abstract: A fault protection method used in a multiphase switching converter which includes a plurality of switching circuits coupled in parallel and a plurality of control circuits configured in a daisy chain. Each control circuit has a first terminal coupled to a phase control signal, a second terminal coupled to a previous control circuit in the daisy chain to receive a phase input signal, and a third terminal coupled to a latter control circuit in the daisy chain to provide a phase output signal.

Abstract: A multiphase switching converter with automatic phase shedding control, 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 respectively configured for driving a corresponding one of the plurality of switching circuits. Each of the control circuit generates a current threshold based on a corresponding sequence information, and compares a current indication signal indicative of a load current of the multiphase switching converter with the current threshold to determine whether to enter into a phase shedding mode.
