Abstract
A multiphase switching converter includes: a plurality of phases, an output capacitor, and a control loop. Each phase includes: a current detection device, a pulse width modulator, a set of switching devices, and an inductor. The control loop is configured to generate a first current signal to the current detection device of each phase of the plurality of phases. The first current signal is proportional to an average current generated by the plurality of phases. The current detection device of each phase provides a signal to a corresponding PWM to control a duty cycle of the set of switching devices to equalize the current generated by each phase and maintain a charge balance on the output capacitor.
