Abstract
A multi-phase buck-boost converter circuit comprises a buck circuit stage, a boost circuit stage, and a control circuit. The buck circuit stage is connected to an input of the buck-boost converter circuit to receive an input voltage. The boost circuit stage includes multiple boost circuits connected in parallel. The boost circuit stage is coupled to the buck circuit stage and an output of the multi-phase buck-boost converter circuit. Each boost circuit includes an inductor coupled to the buck circuit stage. The control circuit operates the multiple boost circuit stages out of phase with respect to each other in a boost mode, operates the buck circuit stage in a buck mode, and operates the multiple boost circuit stages out of phase with respect to each other and operates the buck circuit stage in a buck-boost mode.
