Patent attributes
A controller may control a buck-boost regulator having an input voltage and an output voltage. The controller may include: circuitry that causes the output voltage of the buck-boost regulator to be at the bottom of a pre-determined voltage window when the input voltage goes below the bottom of the pre-determined voltage window: circuitry that causes the output voltage of the buck-boost regulator to be at the top of the pre-determined voltage window when the input voltage goes above the top of the pre-determined voltage window; and circuitry that causes the buck-boost regulator to pass the input voltage through the buck-boost regulator so as to cause the voltage output of the buck-boost regulator to be at the same level as the input voltage when the input voltage is within the pre-determined voltage window.
