Abstract
An electronic driver for operating an illumination device is provided. The electronic driver includes a power converter configured to illuminate the illumination device. The power converter includes a switch capacitor circuit configured to perform at least one of a pulse width modulation dimming and a visible light communication using the illumination device. The switch capacitor circuit includes a plurality of split capacitors operatively coupled in series to a second end of a primary winding of a transformer in the power converter and a control switch operatively coupled to the plurality of split capacitors. The power converter also includes a controller operatively coupled to the control switch and is configured to control the control switch to perform at least one of the pulse width modulation dimming and the visible light communication.
