Abstract
Methods, devices, and integrated circuits are disclosed for controlling a buck-boost converter. In one example, a device is configured to compare an output voltage at a voltage output with a low reference voltage and a high reference voltage. The device may compare a current at an inductor with a low threshold current and a high threshold current. The device may, responsive to the output voltage at the voltage output being lower than the low reference voltage, charge the inductor. The device may, responsive to the current at the inductor reaching the high threshold current, couple the inductor to the voltage output to transfer charge from the inductor to the voltage output. The device may, responsive to either the current at the inductor reaching the low threshold current or the output voltage reaching the high reference voltage, stop transferring charge from the inductor to the voltage output.
