참조 설계 작성자: Integrated Silicon Solution Inc
IS31LT3135-V2GRLS2-EB, Evaluation Board for the IS31LT3135V2 is a dual-channel LED driver. It can function as the main-channel driver or as a sub-channel source. When operating in main mode, the device functions as a constant current source that outputs an adjustable current, via an external resistor, through the main LED. The device is operable with a dropout voltage of 0.1V while driving a 200mA current. When operating as a sub-channel driver, the IC grounds the LED's cathode. The device normally operates with a single channel powered on, allowing for quick switching between the main and sub channel modes. A sweeping power supply that operates between high and low voltages, allows for simple switching between sub/main-channel modes, even during conditions where the UV pin is below the 1.23V UV threshold for IS31LT3135-V2
