<p>PURPOSE: A light emitting device driver circuit and a method for driving light emitting device are provided to miniaturize the light emitting device driver circuit by reducing the size of the circuit area. CONSTITUTION: In a light emitting device driver circuit and a method for driving light emitting device, a powered terminal(22) changes the voltage of an input voltage. The power supply unit supplies an output current to a light emitting device. A control circuit(24) detects the output current of the power supply unit. A control circuit controls feedback the power supply unit. The light emitting device(2) comprises one or more the light emitting diode.</p> |
