A DC to DC converter comprising an inductor, first and second electronically controllable switches and a controller, wherein the first electronically controlled switch is interposed between an input node and a first terminal of the inductor and the second electronically controllable switch extends between a second terminal of the inductor and the ground and where a first rectifier extends between the ground and the first terminal of the inductor and a second rectifier connects the second terminal of the inductor to an output node, wherein the controller controls the operation of the first and second switches to perform voltage step down or voltage step up, as appropriate, to achieve a desired output voltage; and wherein the controller is arranged such that the order in which the first and second switches are operated is maintained irrespective of whether the converter is stepping up the input voltage or stepping down the input voltage.
A DC to DC converter comprising an inductor, first and second electronically controllable switches and a controller, wherein the first electronically controlled switch is interposed between an input node and a first terminal of the inductor and the second electronically controllable switch extends between a second terminal of the inductor and a ground, and where one of a first rectifier and a third electronically controlled switch extends between the ground and the first terminal of the inductor, and one of a second rectifier and a fourth electronically controlled switch connects the second terminal of the inductor to an output node, wherein the controller controls the operation of the first and second switches to perform voltage step down or voltage step up, as appropriate, to achieve a desired output voltage;
A method of operating a DC to DC converter comprising an inductor, first and second electronically controllable switches and a controller, wherein the first electronically controlled switch is interposed between an input node and a first terminal of the inductor and the second electronically controllable switch extends between a second terminal of the inductor and a ground, and where one of a first rectifier and although a third electrically controlled switch extends between the ground and the first terminal of the inductor, and one of a second rectifier and a fourth electrically controllable switch connects the second terminal of the inductor to an output node, wherein the controller is arranged to control the operation of the first and second switches to perform voltage step down or voltage step up, as appropriate, to achieve a desired output voltage;
