Abstract
A charger integrated circuit includes a bidirectional switching converter including first to fourth switching elements connected in series, an inductor connected to a third switching element, and a capacitor connected to a second switching element and the third switching element, and a controller configured to generate, a first PWM signal and a second PWM signal based on sensing signals from the bidirectional switching converter, and a first switching signal controlling first and fourth switching elements based on the first PWM signal in response to an average of an inductor current being positive, a second switching signal controlling second and third switching elements based on the second PWM signal, and generate the first switching signal based on the second PWM signal, and the second switching signal based on the first PWM signal in response to the average value of the inductor current being negative.
