Claim 10:
11. The switching regulator of claim 1, wherein when the target level changes from a relatively higher first target level to a relatively lower second target level, and the feedback signal is higher than the fast response signal, the amplification signal decreases, and the second amplification circuit sources current to increase a slope of the ramp signal, so as to extend a non-conduction time of the power switch; and wherein when the feedback signal is lower than the fast response signal, the amplification signal increases, to decrease the slope of the ramp signal, and the power switch is turned ON, so as to decrease a decrease rate of the output voltage, for mitigating or avoiding an undershoot of the output voltage.
