IS31FL3299 - 3-RGB/9-LED LED DRIVER

Datasheet Summary

Description

The IS31FL3299 is a 9 LED current sink LED driver with 1MHz I2C compatible programming interface.

Each LED can be dimmed individually with 12-bit PWM data and color calibrated with 8-bit DC scaling data, which provides 4096 steps of linear PWM dimming and 256 steps of DC current adjustable levels.

Features

  • a very low operational and shutdown current. Each channel of IS31FL3299 can operate in “PWM & Current Level mode” or “Pattern mode” or “Current Level mode”. In “PWM & Current Level mode”, the output current is set by PWM and 8-bit current level registers. In “Pattern mode”, the timing characteristics for RGB channels output can be individually adjusted to maintain a pre-established pattern sequence without requiring any additional MCU interaction, thus saving valuable system resources. In “Curre.

IS31FL3299 3-RGB/9-LED LED DRIVER GENERAL DESCRIPTION The IS31FL3299 is a 9 LED current sink LED driver with 1MHz I2C compatible programming interface. Each LED can be dimmed individually with 12-bit PWM data and color calibrated with 8-bit DC scaling data, which provides 4096 steps of linear PWM dimming and 256 steps of DC current adjustable levels. All channels output current can be further globally adjusted in 64 steps. The IS31FL3299 operates from 2.7V to 5.5V and features a very low operational and shutdown current. Each channel of IS31FL3299 can operate in “PWM & Current Level mode” or “Pattern mode” or “Current Level mode”. In “PWM & Current Level mode”, the output current is set by PWM and 8-bit current level registers.
