IS31FL3294 Overview
The IS31FL3294 is a 4 LED current sink LED driver programmed via 1MHz I2C patible interface. Each LED can be dimmed individually with 4096 steps PWM data and each current sink has 8-bit DC scaling (Color Calibration) data which allowing 4096 steps of linear PWM dimming and 256 steps of DC current adjustable level. The IS31FL3294 operates from 2.7V to 5.5V.
