AS3665 9 Channel Advanced Command Driven RGB/White LED Driver

The AS3665 is a capacitive low noise charge pump with 9 current sources. The charge pump automatically switches between 1:1 and 1:1.5 modes. The connected current sources have a very low voltage compliance to improve efficiency of the whole system. Three current sources have the possibility to opera.
