Patent number: 7825882Abstract: A dimming method for LED driving circuit is proposed. By temporary switching a pin that is originally used for the input/output of other electric signals to a high impedance node, the dimming control signal may be inputted to dim LEDs. The dimming method comprises the steps of: floating the pin every a period of time to pull the pin's voltage being equal to the dimming control signal; detecting the pin's voltage; and retrieving the dimming control signal in accordance with the detected pin's voltage and thereafter dimming the LEDs.Type: GrantFiled: February 9, 2007Date of Patent: November 2, 2010Assignee: Richtek Technology Corp.Inventors: Wei-Hsin Wei, Shui-Mu Lin, Chien-Sheng Chen, Tsung-Wei Huang, Chin-Chiang Yeh, Chin-Tsung Chen
