Abstract
A DC-DC converter control circuit includes: a slope signal generation circuit that generates a reference voltage by superimposing a slope voltage onto a standard voltage; a comparator that performs comparison of the reference voltage with an output voltage and generates a signal according to a result of the comparison; an oscillator that generates a pulse signal with a substantially constant cycle; and a control signal generation circuit that generates a control signal that turns on a switch based on a comparator output signal and turns off the switch based on the pulse signal.
