Abstract
A power converter having a wide range of an output voltage may include a power supply unit supplying a driving current to a load, a sensing unit sensing a magnitude of the driving current, a first switch controlling an on/off time to control a flow of the driving current, and a control unit operated by being divided into constant current driving and average current driving corresponding to the magnitude of the driving current sensed by the sensing unit. The control unit may controls the power supply unit in the constant current driving so as to make the magnitude of driving current be a predetermined value, and control an on/off time in the average current driving to make an average magnitude of the driving current be the predetermined value.
