www.DataSheet.co.kr Data Sheet A S3 6 6 8 4 C h a n n e l B r e a th li g h t Co n tr o ll er 1 General Description The AS3668 is a 4-channel LED driver designed to produce lighting effects for portable devices. A highly efficient charge pump enables LED driving over full Li-Ion battery voltage range. The device is equipped with an internal program memory, which allows control of LED patterns even without processor control. This helps the whole system to save power and extend for example battery life time in every mobile application. The AS3668 maintains excellent efficiency over a wide operating range by automatically selecting the best charge pump gain based on the LED forward voltage requirements and the device input voltage.
