LOAD DRIVING CIRCUIT AND ILLUMINATION APPARATUS INCLUDING THE SAME |
| 摘要 |
Various embodiments may relate to a load driving circuit and an illumination apparatus including the same. The load driving circuit includes a Single-Ended Primary Inductor Converter (SEPIC) converter adapted to convert an input system voltage into a DC output voltage, and a BUCK converter 200 adapted to regulate a current and provide the regulated current to a load. The load driving circuit further includes a first diode and a second diode which are connected so that the SEPIC converter and the BUCK converter share one switch. According to various embodiments, it is possible to obtain constant current output characteristics and high power factor with a simple circuit structure and a low cost. |
