GENERAL DESCRIPTION
Three current sources have the possibility to operate either from VBAT or VCP (especially useful for red LEDs). The internal control is done by command based pattern generators implemented by three sequencers. These commands are optimized for lighting applications (e.g. ramp up brightness logarithmically). It includes high level commands like conditionals jumps and variables. Any of the three sequencers can be dynamically mapped to any of the 9 PWM generators for the LEDs. The AS3665 supports an audio input and sophisticated light patterns can be controlled by internal digital filters. 2 Datasheet, Confidential 9 Channel Advanced Command Driven RGB/White LED Driver 2 Key FEATURES
