Abstract
A system includes an inductor having first and second terminals. First and second transistors have first terminals connected to the first and second terminals of the inductor, respectively, and second terminals connected to a power supply and a common potential, respectively. Third and fourth transistors have first terminals connected to the first and second terminals of the inductor, respectively, and second terminals providing first and second output voltages of first and second polarities, respectively. First and second feedback circuits generate first and second feedback signals based on the first and second output voltages, respectively. A first control circuit controls the first and third transistors based on the second feedback signal and not based on the first feedback signal. A second control circuit controls the second and fourth transistors based on the first feedback signal and not based on the second feedback signal.
