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 switch controller for switching power supply is coupled to an auxiliary winding of the switching power supply through a detecting resistor. The switch controller provides a detecting current passing through the detecting resistor for keeping the voltage level of a detecting signal transmitted by the detecting resistor higher than a predetermined voltage. In this way, the switch controller can avoid the latch-up phenomenon caused by receiving the detecting signal of the negative voltage level. In addition, the switch controller can detect the magnitude of an input voltage of the switching power supply by means of the detecting current, and accordingly control the operation of the switching power supply.

Abstract: A high voltage charging circuit is provided with the ability of rapid charging. The circuit is composed of a turn-on control circuit, a turn-off control circuit and a transistor. The turn-on control circuit is adopted to set a turn-on time of a transistor such that the transformer may store magnetic energy, while the turn-off control circuit is used to set a turn-off time of the transistor such that the transformer may release the magnetic energy to charge a high voltage capacitor. Smaller inductance reduces the turn-on time of the power transistor owing to the maximum current of the primary side of the transformer. Therefore, a small-sized transformer may be employed to reduce the volume of the charging circuit with nonoccurrence of saturation.
