Abstract
A control circuit for a buck-boost circuit includes an inductor current sensor and an input current generator. The input current generator accepts a signal from the inductor current sensor and outputs a synthesized and integrated signal representing the average input current to the buck-boost circuit. The input current generator averages the inductor current signal or a zero signal based on the state of the buck switch in the buck-boost circuit.
