摘要： A charge pump structure (1) with regulated output voltage comprises an output terminal (OUT) to provide the output voltage (Voutmain) and a charge pump (10) to generate the output voltage (Voutmain) as a function of an input supply voltage (Vsup). The charge pump structure (1) further comprises a control circuit (30) to limit a level of the output voltage (Voutmain). The control circuit (30) is configured to generate a control voltage (Voutref), wherein the level of the output voltage (Voutmain) is controlled by the control voltage (Voutref) such that the output voltage (Voutmain) does not exceed a threshold value.

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.
