More Information
Summary:In the present invention, disclosed are an improved gamma voltage supplying circuit capable of stably supplying a gamma voltage by corresponding to the variation of an external power source and a power management IC adopting the same. The present invention includes the gamma voltage supplying circuit which generates a regulation voltage using an internal voltage without the influence of a load variation in a source driver IC and generates the gamma voltage using the regulation voltage. 본 발명은 외부 전원의 변화에 대응하여 감마 전압을 안정적으로 제공할 수 있도록 개선한 감마 전압 제공 회로와 그를 채용한 전원 관리 집적 회로를 개시하며, 감마 전압 제공 회로를 포함하고, 감마 전압 제공 회로는 소스 드라이버 집적 회로의 부하 변동에 영향을 받지 않는 내부 전압을 이용하여 레귤레이션 전압을 생성하고 레귤레이션 전압을 이용하여 감마 전압을 생성하도록 구성된다.
