<p>The present invention relates to a voltage tracking circuit and to an over voltage protection buck converter having the same. According to an embodiment, the present invention tracks the variation of input voltage and outputs the voltage by generating output voltage which reflects the variation of the input voltage when the input voltage reaches within a specific range. The present invention generates the output voltage which reflects the variation of the voltage of the light source of a lighting device and controls the operation of the lighting device according to the output voltage.</p> |
