Abstract
The present invention discloses a control apparatus, which not only accepts multiple dimming control signals, but also combines the signals in analog manner. By means of this, an inevitable analog to digital converter in a conventional voltage multiple dimming control apparatus can be saved without hurting the performance of generation of pulse width modulation signals. Compared with the conventional arts, the present invention further exhibits reduction in view of chip size and power consumption.
