ABSTRACT:
A switching regulator includes an inductor, first and second switches, a first rectifier to allow current flowing from a negative voltage output terminal to a connection node between the inductor and the first switch, a second rectifier to allow current flowing from a positive voltage output terminal to a connection node between the inductor and the second switch, a third switch, a first capacitor connected between the negative voltage output terminal and ground, a second capacitor connected between the positive voltage output terminal and ground, and a controller to control switching operations of the first, second and third switches to make each voltages at the negative and positive voltage output terminals to be corresponding predetermined voltages. The control circuit switches the first and second switches on/off simultaneously to make a sum of absolute values of voltages at the negative and positive voltage output terminals a predetermined voltage value.
