Abstract
In one form, an apparatus comprises a buck-boost converter circuit, a ripple emulator circuit, a ripple based controller circuit, and a switch control circuit. The buck-boost converter circuit includes a plurality of switches to be coupled to an inductor, and is configured to generate a regulated output voltage responsive to an input voltage. The ripple emulator circuit is configured to emulate inductor current ripple for a buck phase and a boost phase of the buck-boost converter to provide an emulated inductor current ripple. The ripple based controller circuit is configured to generate a hysteretic control signal responsive to the emulated inductor current ripple and the output voltage. The switch control circuit is configured to generate control signals for driving the plurality of switches responsive to the hysteretic control signal and a clock signal.
