Abstract:
A method for controlling a power switch of a power converter includes: detecting whether a zero current event occurs; generating an error signal; generating an ramp signal having a slope proportional to a ratio of an on time during which of the power switch is turned on in a previous switching cycle to a time length of the previous switching cycle; comparing the ramp signal with the error signal; turning on the power switch when the zero current event occurs; and turning off the power switch and rapidly lowering the level of the ramp signal when the ramp signal is greater than or equal to the error signal.

Claim (Index 21):
The method of  claim 17 , wherein the operation of rapidly lowering the level of the ramp signal (RAMP) comprises:\n providing a third switch ( 370 ) configured to be coupled between the output terminal of the transconductance amplifier ( 350 ) and a fixed-voltage terminal; and turning on the third switch ( 370 ) when the ramp signal (RAMP) is greater than or equal to the error signal (COMP).
