AS3527 - Advanced Audio Processor System

General Description

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.

The connected current sources have a very low voltage compliance to improve efficiency of the whole system. 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.
