Abstract
Disclosed is a power supply unit including a DC-DC converter including an output terminal and resistor coupling terminal and an external resistor coupled to the resistor coupling terminal, where the DC-DC converter includes a first power generation unit which outputs a predetermined current to the output terminal, and a sensing circuit unit that includes a sensing resistor located between the first power generation unit and the output terminal and stops an operation of the first power generation unit depending on a current value flowing in the sensing resistor. A power supply unit and an organic light emitting display including the power supply unit include a sensing circuit unit that stops operation of the power supply unit to prevent an additional damage when an abnormal current occurs.
