Abstract: A method of operating a buck-boost converter including an inductor and a capacitor includes; operating the buck-boost converter in boost mode until a level of an input voltage applied at an input node of the buck-boost converter reaches a desired level of an output voltage apparent at an output node of the buck-boost converter, and after the level of an input voltage reaches the desired level of the output voltage, operating the buck-boost converter in buck mode, wherein operating the buck-boost converter in buck mode and operating the buck-boost converter in boost mode overlap at least in part temporally proximate a point at which the level of the input voltage exceeds the level of the output voltage.

Abstract: A bi-directional voltage positioning circuit includes a voltage to current converter, a current mirror circuit and a switch. The voltage to current converter converts a sensing voltage to a first current, and the sensing voltage is sensed based on a current flowing through an output coil connected between a switching node and an output node. The current mirror circuit mirrors the first current to generate a second current and a third current, the second current is N times greater than the first current, the third current is M times greater than the first current, and N and M are real numbers greater than zero. The switch provides a feedback node with one of the second current and third current in response to a switching control signal, and an output voltage of the output node is divided at the feedback node.
