| description | The present invention relates to a DC-DC converter and an organic electroluminescence display device using the same. A DC-DC converter according to an embodiment of the present invention comprises: a switching module for converting an input voltage into a first voltage through switching operations of a plurality of switches turned on/off in response to a pulse width modulation (PWM) signal and outputting the first voltage; a sensing unit for sensing a driving current supplied to a load which receives the first voltage; and a control module for controlling the switching module by generating the PWM signal. The control module is configured to adaptively control a turn-on resistance of the switching module according to the sensing result of the sensing unit. According to the present invention, it is possible to provide the DC-DC converter and the organic electroluminescence display device which adaptively operate according to a load condition and thus having the optimum efficiency. |
