DC-DC CONVERTER, ORGANIC LIGHT EMITTING DISPLAY HAVING THE DC-DC CONVERTER AND METHOD FOR OPERATING THE DC-DC CONVERTER |
摘要 |
A direct current-to-direct current converter includes: a buck-boost unit configured to receive an input power source supplied through an input power line, where the buck-boost unit outputs a first power source obtained by boosting the input power source and a second power source obtained by dropping the input power source; and a short-circuit sensing unit connected to the input power line and a control signal line, and configured to sense a short circuit between the input power line and the control signal line, where the short-circuit sensing unit turns off the buck-boost unit when the short circuit between the input power line and the control signal line occurs. |
