DC-DC CONVERTER AND ORGANIC LIGHT EMITTING DISPLAY INCLUDING THE SAME

摘要

PURPOSE: A DC-DC converter and an organic electroluminescent display device including the same are provided to perform normal operation with additional damage even though a feedback wire is disconnected. CONSTITUTION: A DC-DC converter (60) includes a first power generating unit (110) outputting first power (ELVDD) to a first output terminal, a second power generating unit (120) outputting second power (ELVSS) to a second output terminal, a selecting unit (130) selectively delivering a voltage from a feedback wire to a feedback terminal. [Reference numerals] (110) First power generating unit; (120) Second power generating unit; (130) Selecting unit; (70) Power supply unit
