Abstract:
A switching power supply apparatus of each embodiment includes: a switch circuit configured to supply a pulse output to a load; a drive signal control circuit configured to perform ON/OFF driving operation of the switch circuit according to a duty ratio of a PWM signal; an error detection amplifier configured to compare output voltage supplied to the load and reference voltage and generate an error detection signal; a comparator configured to generate the PWM signal by comparison between a slope signal that starts level change in a cycle of the PWM signal and the error detection signal and give the PWM signal to the drive signal control circuit; and a spread spectrum correction circuit configured to generate an offset corresponding to the fluctuation of the cycle of the PWM signal and add the generated offset to the slope signal or the error detection signal.

Claim (Index 3):
The switching power supply apparatus according to  claim 2 , further comprising a slope compensation signal generation circuit configured to give a slope compensation signal for prevention of subharmonic oscillation to the first adder.
