18-CHANNEL LED DRIVER GENERAL DESCRIPTION IS32FL3238 is an LED driver with 18 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 designed to be 78mA, which can be adjusted by one 8-bit global control register. Proprietary programmable algorithms are used in IS32FL3238 to minimize audible noise caused by the MLCC decoupling capacitor. All registers can be programmed via a high speed I2C...
