Abstract
A method includes driving a first transistor to conduct a first current into an inductor when conductive and driving a second transistor to conduct a second current into the inductor when conductive. A first sense current is generated in response to the first current and a copy of the second current. A second sense current is generated in response to the second current and a copy of the first current. The first sense current is adjusted in response to the copy of the second current when the first transistor is nonconductive. The second sense current is adjusted in response to the copy of the first current when the second transistor is nonconductive. On times of the first and second transistors are controlled in response to a sum of the first and second sense currents.
