Abstract
A controller for a multiphase switching converter has a voltage control circuit, a total current control circuit, a frequency divider and a plurality of sub control circuits. The voltage control circuit provides an on-time control signal based on an output voltage. The total current control circuit provides a current control signal based on a total current flowing through the plurality of switching circuits. The frequency divider receives the on-time control signal, and provides a plurality of frequency division signals based on the on-time control signal. The plurality of sub control circuits provides a plurality of switching control signals to control the plurality of switching circuits respectively. Each of the plurality of sub control circuits receives one of the plurality of frequency division signals and the current control signal, and provides one of the plurality of switching control signals.
