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 adjusted voltage by multiplying a setting voltage by 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; performing a low-pass filtering operation on the adjusted voltage to generate a filtered signal; providing a transconductance amplifier for converting the filtered signal into a ramp 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.
