Abstract
A power converter includes an inductor, boost and buck circuits, and a controller circuit. The controller circuit is configured to determine a current through the inductor, generate a buck reference for comparison with the current to control operation of the buck circuit, calculate a variable offset based upon input and output potentials of the power converter and apply the variable offset to the buck reference to generate a boost reference, compare the boost reference with the current to control operation of the boost circuit, and, based upon comparisons of the current with the buck reference and the boost reference, respectively, operate the boost circuit and the buck circuit.
