Abstract:
A switching power converter circuit includes a power switch for operating an inductor to convert the input voltage to the output voltage to drive a load circuit; and a control circuit, including: a pulse width modulation circuit comparing an output related signal with a ramp signal to generate a pulse width modulation signal for controlling the power switch, wherein the output related signal is related to the output voltage; an error amplifier circuit generating an error amplified signal according to a difference between the output related signal and a reference signal; and a ramp signal generation circuit generating the ramp signal, wherein an amplitude of the ramp signal is determined according to the input voltage and the output voltage; and/or the slope of the ramp signal is determined according to the error amplified signal.

Claim (Index 14):
The switching power converter circuit of  claim 2 , wherein the ramp signal generation circuit includes:\n a first slope control circuit, configured to operably generate a slope adjustment current according to the error amplified signal; and an integration capacitor coupled to the first slope control circuit to generate the ramp signal, wherein one of the ascending ramp portion and the descending ramp portion is generated according to the slope adjustment current to have the first slope and the first slope is determined according to the slope adjustment current in a corresponding ascending or descending period of the ramp signal.
