Abstract
A converter constituted of: an inductor; a plurality of electronically controlled switches; and a control circuitry arranged to operate in a buck-boost mode responsive to the output voltage of the converter being within a predetermined range of the input voltage of the converter, the control circuitry arranged in the buck-boost mode: responsive to a current flowing through the inductor being lower than a predetermined low current threshold, to control the switches to couple the inductor between the input voltage and a common potential; responsive to the current flowing through the inductor being greater than a predetermined medium current threshold, to control the switches to couple the inductor between the input voltage and the output voltage; and responsive to the current flowing through the inductor being greater than a predetermined high current threshold, to control the switches to couple the inductor between the output voltage and the common potential.
