DC-DC converter and organic light emitting display device using the same

摘要

A DC-DC converter and an organic light emitting display device using the same. Here, a DC-DC converter (500) is provided with a voltage sensor (400) for sensing a battery voltage outputted from a battery (700). A regulator (510) receives the battery voltage from the battery (700). When the battery voltage is a set value or less, the regulator (510) is stopped from bypassing the battery voltage. When the voltage of the inputted power source exceeds the set value, the regulator (510) is driven to lower the battery voltage. When the battery voltage is the set value or less, a controller (600) controls the driving of the regulator (510). A power generator receives the regulated battery voltage to output a first pixel power source and a second pixel power source.
