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. The maximum output current of each channel is 38mA, adjusted by one 8-bit global control register. It features proprietary programmable technology to minimize audible noise caused by MLCC decoupling capacitors and supports a high-speed 1MHz I2C interface.
