Abstract
A method may include operating a DC-DC switch converter in a forced continuous conduction mode in which for each switching cycle of the switch converter during the forced continuous conduction mode, the switch converter operates in a series of phases including: a first phase in which an inductor current flowing in an inductor of the switch converter increases from zero to a controlled positive current magnitude with respect to a first terminal and a second terminal of the inductor; a second phase in which the inductor current decreases from the controlled positive current magnitude to approximately zero; a third phase in which the inductor current decreases from approximately zero to a controlled negative current magnitude with respect to a first terminal and a second terminal of the inductor; and a fourth phase in which the inductor current increases from the controlled negative current magnitude to approximately zero.
