Abstract: Integrated circuits for controlling power supplies and relevant control methods are disclosed. A controller generates a control signal to control a power switch. A feedback pin of an integrated circuit receives an external feedback signal representing an output voltage signal of a power supply. Controlled by the control signal, a transferring circuit transfers the feedback signal to the controller when the power switch is off. When the power switch is on, a clamping circuit clamps the voltage of the feedback signal at a predetermined value to avoid the controller from being influenced by the feedback signal.

Abstract: A pulse width modulation (PWM) control circuit is applied to a power converter with a charging capacitor. The PWM control circuit includes a PWM signal generator, a first comparator, and a reference voltage modulator. A PWM signal generator generates a PWM signal to control a power switch in the power converter. Two input terminals of the first comparator respectively receive a first reference voltage and a sensing voltage, which is proportional to a primary-side current of a transformer. When the power switch is turned on and the sensing voltage rises to the level of the first reference voltage, the first comparator outputs a first control signal to the PWM signal generator. Then, the PWM signal generator outputs a signal to turn off the power switch. The reference voltage modulator outputs the first reference voltage according to a feedback voltage relative to the output voltage of the power converter.
