IS32FL3207 18-CHANNEL LED DRIVER WITH 16-BIT PWM June 2020 GENERAL DESCRIPTION FEATURES IS32FL3207 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 a 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 can be adjusted by one 8-bit global control register.   Proprietary programmable algorithms are used in IS32FL3207 to minimize audible noise caused by the MLCC decoupling capacitor. All registers can be programmed via a high speed I2C (1MHz). IS32FL3207 can be turned off with minimum current consumption by either pulling the SDB pin low or by using the software shutdown feature. IS32FL3207 is available in WFQFN-28 (5mm × 5mm) package. It operates from 2.7V to 5.5V over the temperature range of -40°C to +125°C.           2.7V to 5.5V supply Accuracy between channels and ICs:
