AS3665 - 9 Channel Advanced Command Driven RGB/White LED Driver

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.

Key Features

  • High efficiency capacitive 150mA charge pump with 1:1, 1:1.5 and 1:2 modes with automatic mode switching; 1:2 mode can be disabled 9 Channel High Side 20mA Current sources - Less than 50mV at 10mA dropout voltage - LED7,8,9 either powered by VBAT or VCP Advanced Command based Pattern Generator - 96 x 16 bits program memory - Dedicated lighting commands like logarithmic fade - Programming control and conditional jumps Audio Controlled Lighting with internal digital filters 3 Sequencers - Dynamica.

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 operate either from VBAT or VCP (especially useful for red LEDs).
