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.

Abstract: Methods, devices, and circuits are disclosed delivering a first level of output current to one or more loads in a buck-boost converter comprising an inductor. The methods, devices, and circuits may further be disclosed applying, in response to an indication of an altered output current requirement to one or more loads in a buck-boost converter comprising an inductor, a change in a supplied reference voltage to one or more elements including a feedforward control element, wherein applying the change in the supplied reference voltage to the feedforward control element causes an adjustment of the output current from the first level to a second level corresponding to the altered current output requirement.
