IS31FL3237 Datasheet | ISSI

DESCRIPTION The IS31FL3237 is an LED driver with 36 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 38m A, 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 IS31FL3237 can be shut down with minimum current consumption by either pulling the SDB pin low or by using the software shutdown feature . The IS31FL3237 is available in QFN-44 (5mm×5mm) package. It operates from 2.7V to 5.5V over the temperature range of -40°C to +125°C. December 2018 FEATURES - 2.7V to 5.5V VCC...
