  • Patent number: 8093877
    Abstract: A transient voltage compensation apparatus and a power supply using the same are provided. The power supply mainly uses a compensation circuit coupled between an input terminal and an output terminal of a power converter. When a load of the power supply is switched in a very short time, a power coupled to the compensation circuit is retrieved to compensate the output of the power supply, such that the output voltage is kept steady, and the transient response of the power supply is increased.

  • Publication number: 20070273346
    Abstract: A voltage regulator circuit with over-current protection, which includes a linear regulator, a voltage controller, and an over-current protection circuit. The linear regulator includes a converter and a driver. The converter is connected to a voltage input terminal and a voltage output terminal. An output terminal of the driver is connected to the converter for controlling the operation of the converter. The voltage controller is connected to the voltage output terminal, the output terminal and a first input terminal of the driver, respectively, for providing a feedback voltage. The over-current protection circuit is connected to the output terminal of the driver and the linear regulator. The over-current protection circuit detects the output voltage of the driver for comparing with a comparison voltage. When the output voltage is larger than the comparison voltage, the over-current protection circuit controls the driver to turn off the converter.
