The converting circuit is configured to generate an output voltage by adjusting an input voltage in a buck mode, a boost mode, and a buck-boost mode. The ripple injector is configured to generate a ripple based on switching signals corresponding to switching operations of the converting circuit. The hysteresis comparator outputs at least one switching control signal by comparing an output control voltage with a feedback voltage generated by adding the ripple to a divided voltage generated by performing a voltage division on the output voltage. The switching controller is configured to change a current flow path of the converting circuit based on the at least one switching control signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Buck-boost converters and power management integrated circuits including the same","description":"A buck-boost converter includes: a converting circuit; a ripple injector; a hysteresis comparator; and a switching controller.
