Abstract
A switching regulator and a method of regulating voltage by means of a switching regulator, includes a regulator switch, a smoothing filter, and a first voltage feedback loop from an output of he regulator to a control line of the switch. The first feedback loop may include a hysteresis comparator or a comparator and a frequency reference connected to the control line of the switch. The first feedback loop uses the A.C. ripples at the output of the smoothing filter as a ramp signal feedback to substantially instantaneously correct output voltage. A second voltage feedback is further employed to stabilize the output voltage. The smoothing filter employs an LC circuit and the regulator is provided with means for providing an inductor current path when the switch is opened. The regulator may, further, include a current feedback loop.
