Abstract
A non-inverting buck boost voltage converter includes a buck boost voltage regulation circuitry for generating a regulated output voltage responsive to an input voltage. A current sensor monitors an input current to the buck boost voltage regulation circuitry. Buck boost mode control circuitry controls the buck boost voltage regulation circuitry using peak current mode control in a buck mode of operation and valley current mode control in boost mode of operation responsive to the monitored input current.
