Abstract: An electronic device and control method used therein. The electronic device comprises a tuner, a video capture device, and a potential selector. When a first potential is applied with the potential selector, both the tuner and the video capture device are powered by a first power source of the first potential, and, when a second potential is applied with the potential selector, only the video capture device is powered by a second power source of the second potential.

Abstract: A boost converter includes a first boost conversion unit and a second boost conversion unit. Coils of the first boost conversion unit and the second boost conversion unit are coupled with each other. Due to coupling of the coils, the second boost conversion unit releases energy while the first boost conversion unit stores energy in a period of time. Furthermore, due to coupling of the coils, the first boost conversion unit releases energy while the second boost conversion unit stores energy in another period of time. The two boost conversion units operate alternately, thereby adjusting switching loss and averaging output power of components. Furthermore, as switching frequency increases, the coil inductance, as well as the capacitance required in the two boost conversion units can be reduced correspondingly, thus substantially enhancing responses of the two boost conversion units as a whole.

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.
