Abstract
A controller for a switching converter converting an AC input voltage into an output voltage. The controller includes a light load determining circuit, a voltage comparing circuit, a window generator and a switch control circuit. The light load determining circuit generates a light load determining signal indicating whether the switching converter operates in a light load mode. The voltage comparing circuit compares a first feedback voltage signal indicative of the output voltage with a first and a second reference voltage signals respectively to generate a first square wave signal. The window generator generates a second square wave signal based on a second feedback voltage signal indicative of the AC input voltage. The switch control circuit generates a switch control signal to control the power operation of the switching converter based on the light load determining signal, the first square wave signal and the second square wave signal.
