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 21):
The converter control circuit of  claim 17 , wherein the pulse width modulation circuit includes:\n a comparison circuit, configured to operably compare the output related signal with the ramp signal to generate a comparison output signal; and a constant time generation circuit, configured to operably generate a constant time signal according to the comparison output signal, the constant time signal defining a constant ON-time for controlling the power switch to be ON for a constant duty period which is substantially equal to the constant ON-time in each cycle period.
