Abstract
A current mode buck-boost converter has an input terminal, an output terminal, and an output capacitor coupled to the output terminal. The input terminal is used to receive an input voltage, and the output terminal is for producing the output voltage. The current mode buck-boost converter comprises a voltage converter and a control circuit. The voltage converter comprises an inductor. The control circuit is for detecting the current passing through the inductor to determine the electric energy transmitted to the output terminal by the voltage converter. Accordingly, the current mode buck-boost converter has fast response, and the electrical energy can be recycled and stored to the voltage source when the current mode buck-boost converter operates in down-tracking process.
