SMOOTH TRANSITIONING BUCK-BOOST DC-DC CONVERTER
Abstract:
A buck-boost DC-DC converter, which includes converter control circuitry, converter switching circuitry, and a first inductive element, is disclosed. The converter control circuitry provides a buck mode timing signal and a boost mode timing signal. The converter switching circuitry provides a switching output signal. During a buck mode of the buck-boost DC-DC converter, when a buck pulse-width of the switching output signal is less than a buck pulse-width threshold, the buck pulse-width is limited based on both the buck mode timing signal and the boost mode timing signal. During a boost mode of the buck-boost DC-DC converter, when a boost pulse-width of the switching output signal is less than a boost pulse-width threshold, the boost pulse-width is limited based on both the buck mode timing signal and the boost mode timing signal. The first inductive element receives and filters the switching output signal to provide a converter output signal.
