Abstract
A self-oscillating switching regulator includes an inductor which is switched across the input or output depending, respectively, on whether a control voltage does not or does exceed a predetermined threshold. The control voltage is generated from a predetermined sum of the output voltage and a voltage dependent upon the inductor current when the inductor is connected across the input.
