PURPOSE: A dimmer circuit is provided to decrease effect of noise while transmitting a voltage value by transmitting a voltage value via data line using a plurality of MICOMs and to accurately control brightness and to increase usability by controlling output voltage through a feedback unit by comparing a voltage value corresponding to input brightness and an output voltage value. CONSTITUTION: A dimmer circuit includes a first MICOM(100) capable of outputting a voltage value corresponding to a signal by receiving an input signal, an illumination unit(130) connected with an output side of the first MICOM(100) and a feedback unit(140) providing feedback to the first MICOM(100) after measuring the output voltage value output from the first MICOM(100).
