Abstract
A switching regulator control circuit, having: a slope circuitfor generating a slope voltage Von the basis of a clock signal CLK of a prescribed frequency; an error amplifierfor generating an error signal Vc corresponding to the difference between a reference voltage Vand a voltage Vcorresponding to the output voltage of a switching regulator; a comparatorfor comparing the error signal Vc and the slope voltage V; and an RS flip-flopset on the basis of the clock signal CLK and reset by a signal outputted by the comparator. The timing at which the RS flip-flopis set is delayed with respect to the timing at which the sloping of the slope voltage Vis started.
