IS32FL3238
IS32FL3238 is 18-CHANNEL LED DRIVER manufactured by Lumissil.
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 78m A, 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 (1MHz).
IS32FL3238 can be turned off with minimum current consumption by either pulling the SDB pin low or by using the software shutdown feature
.
IS32FL3238 is available in e TSSOP-28 package. It operates from 2.7V to 5.5V over the temperature range of -40°C to +125°C
