  • LED driver circuit with a boosted voltage output
    Patent number: 6486726
    Abstract: A Light Emitting Diode (LED) driver circuit with a boosted voltage output for driving an LED from a voltage power supply having a voltage that is lower than the turn “on” voltage of the LED is provided. A charge pump provides the boosted voltage output of the LED driver circuit. During operation, the LED driver circuit switches the LED on and off at a predetermined frequency such that a human observer perceives the LED to be continuously turned “on”. In one embodiment, the LED driver circuit further comprises a current regulator for regulating the current supplied to the LED. In another embodiment, the LED driver circuit comprises a voltage regulator to regulate the boosted voltage output of the LED driver circuit.
