IS31FL3237 - 36-CHANNEL LED DRIVER

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.

IS31FL3237 36-CHANNEL LED DRIVER GENERAL 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 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).
