Datasheet Summary
24-CHANNEL LED DRIVER
GENERAL DESCRIPTION The IS31FL3239 is an LED driver with 24 constant current channels. Each channel can be pulse width modulated (PWM) by 16 bits for smooth LED brightness control. In addition, each channel has an 8-bit output current control register which allows fine tuning the current for rich RGB color mixing, e.g., a pure white color LED application. The maximum output current of each channel is 38mA, which can be adjusted by one 8-bit global control register. Proprietary programmable technology is used to minimize audible noise caused by MLCC decoupling capacitors. All registers can be programmed via a high speed I2C (1MHz). The IS31FL3239 can be shut...
