DC/DC CONVERTER AND CONTROLLER THEREOF

摘要

A DC/DC converter for driving a load is provided. The DC/DC converter includes an inductor, a switch, a capacitor and a rectifier element. The switch and the inductor are coupled in series between a first common level and a second common level. The capacitor and the rectifier element are coupled in series between the first and second terminal of the switch or the inductor. The load is coupled between a coupling point of the capacitor and rectifier element and the second common level, wherein the coupling point of the capacitor and rectifier element outputs an output voltage to drive the load. A control terminal of the switch is switched between open circuit state and short circuit state according to a control signal.
