Zusammenfassung:	The present specification discloses an LED driving apparatus in which a voltage drop due to a common impedance is improved. The LED driving apparatus according to the present specification configures a circuit by combining NMOS or PMOS so that a positive power source or negative power source is not connected to a source terminal of a MOSFET. Accordingly, a common impedance effect in the positive power source or negative power source may be removed. 본 명세서는 공통 임피던스에 의한 전압 강하가 개선된 LED 구동 장치를 개시한다. 본 명세서에 따른 LED 구동 장치는 양전원 또는 음전원이 모스펫의 소스단과 연결되지 않도록 NMOS 또는 PMOS를 조합하여 회로 구성한 것을 특징으로 한다. 이를 통해 하며 양전원 또는 음전원에서 공통 임피던스 영향을 제거할 수 있다.
