IS31FL3299 - Lumissil

IS31FL3299 3-RGB/9-LED LED DRIVER

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 .

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 “Current Level mode”, the output current is set by 8-bit current level register. IS31FL3299 is available i.
