Abstract
A method for controlling a voltage converter includes the following steps. A feedback compensation signal is generated based on an output voltage of the voltage converter. An output representation signal is compared with a first threshold and a second threshold. A switch control signal to control the turn-on and turn-off of a power circuit of the voltage converter is adjusted based on an ultra-light load feedback value when the output representation signal is less than the first power threshold. The switch control signal is adjusted based on the feedback compensation signal when the output representation signal is greater than the first power threshold. The second threshold is greater than the first threshold, and the ultra-light load feedback value is greater than the feedback compensation signal when the output representation signal is equal to the second threshold.
