Abstract
Operating buck-boost converters. At least some of the example embodiments are methods including: producing an output voltage and an output current from the buck-boost converter; sensing a feedback parameter by a sensor disposed between an inductor of the buck-boost converter and a load; generating an error signal based on the feedback parameter; running the buck-boost converter in a buck-only mode, the buck-only mode operating at a switching frequency and during periods of time when the error signal is within a first range of values; and changing to a buck-boost mode when the error signal is in a second range of values, the buck-boost mode operating at the switching frequency; and transitioning to a boost-only mode when the error signal is in a third range of values, the boost-only mode operating at the switching frequency.
