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 voltage converter for providing an output voltage signal at an output port according to an input voltage signal is disclosed. The voltage converter comprises a feedback circuit, a transmission switch circuit, a voltage converting circuit, and a pre-bias circuit. The feedback circuit generates a feedback voltage signal according to the output voltage signal.

Abstract: A high voltage charging circuit includes an activation control circuit, an inactivation control circuit and a power transistor. The activation control circuit is used for controlling an ON time period of the power transistor to enable the transformer to store excited-magnetic energy; the inactivation control circuit is used for controlling an OFF time period of the power transistor to make the transformer to release the excited-magnetic energy and use the excited-magnetic energy to charge the high voltage capacitor. Since the user can select a smaller Lp to keep constant the maximum value IP,max for the primary side current IP, the period tON can be made smaller as well, which means that a transformer 14 with a smaller volume can be utilized to reduce the entire size of the high voltage charging circuit.

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.
