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 1):
A switching power converter circuit, comprising:\n an inductor; a power switch, configured to operably switch connections of the inductor with an input voltage and an output voltage so as to convert the input voltage to the output voltage to drive a load circuit; and a control circuit, including:\n a pulse width modulation circuit, configured to operably compare 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; and \n a ramp signal generation circuit, configured to operably generate the ramp signal, wherein the ramp signal is generated by one or more of the following ways: \n (1) that the ramp signal generation circuit determines an amplitude of the ramp signal according to the input voltage and the output voltage; and/or \n (2) that the control circuit further includes an error amplifier circuit configured to operably generate an error amplified signal according to a difference between a signal to be regulated in the switching power converter circuit and a reference signal, and the ramp signal generation circuit determines a first slope of the ramp signal according to the error amplified signal.
