摘要： The present invention relates to a remote control IC having a circuit for pumping up current of an output port and a remote controller implemented to be capable of operating with one battery of about 1.5V using the IC. In the remote controller, an infrared LED (310) emits light through the remote control IC, so that signals are transmitted to devices to be controlled such as a television set. The output, port according to the present invention has an output current pumping circuit (320,300) for detecting a level of power voltage according to the drop of the power voltage, boosting the power voltage, and supplying a voltage boosted higher than the power voltage to the gate of a MOS transistor (300) to obtain output current of high voltage. The output current pumping circuit comprises a power voltage detection unit (322) for determining a level of the power voltage, a boost circuit unit (321) for boosting the power voltage depending on an effective signal of the power voltage detection unit (322), and a data conversion unit (323) for receiving the changed power voltage and controlling the changed power voltage in response to a transmission signal to supply gate voltage of the MOS transistor for outputting final current.

摘要： A load control device adapted to be coupled between an AC power source and an electrical load for controlling the power delivered to the load includes a power supply having an energy storage capacitor and a charge pump circuit adapted to conduct an input charging current through the load and to conduct an output charging current through the energy storage capacitor to thus generate a DC supply voltage across the energy storage capacitor, where the output charging current has a magnitude greater than the input charging current. The charge pump circuit includes a switched capacitor operable to charge through the load during a first half-cycle, and to discharge into the energy storage capacitor in a second, subsequent half-cycle. The charge pump circuit operates at line frequency and the magnitude of the input charging current is substantially small so as to avoid generating noise in a noise-sensitive circuit of the load control device.

摘要： A boost DC-DC converter includes: an input terminal; an output terminal; a first boost circuit configured to generate, from an input power to the input terminal, a first boosted power having a higher voltage than a voltage of the input power, and outputs the generated first boosted power from the output terminal; a second boost circuit configured to generate, from the input power, a second boosted power having a higher voltage than the voltage of the input power; and a storage capacitor configured to store the second boosted power as a storage power, and supply the storage power to the first boost circuit as an operation power source. The first boost circuit is configured to start a boost operation with the storage power when a voltage of the storage power is equal to or higher than a minimum operation voltage of the first boost circuit.
