Abstract
Methods, devices, and integrated circuits are disclosed for applying an active output voltage discharge for a buck-boost converter. One example is directed to a method of operating a buck-boost converter that comprises an inductor, an output capacitor, and an output. The method includes receiving an indication of an altered output voltage requirement in the buck-boost converter. The method further includes deactivating a control loop in the buck-boost converter. The method further includes applying an active discharge of voltage from the output capacitor through the inductor to ground, thereby altering the voltage at the output of the buck-boost converter from a first output voltage to a second output voltage that corresponds to the altered output voltage requirement. The method further includes reactivating the control loop.
