Overview

IS31FL3236 is comprised of 36 constant current channels each with independent PWM control, designed for driving LEDs. The output current of each channel can be set at up to 38mA (Max.) by an external resistor and independently scaled by a factor of 1, 1/2, 1/3 and 1/4. The average LED current of each channel can be changed in 256 steps by changing the PWM duty cycle through an I2C interface. The chip can be turned off by pulling the SDB pin low or by using the software shutdown feature to reduce power consumption. IS31FL3236 is available in QFN-44 (5mm × 5mm) and eTQFP-48 package. It operates from 2.7V to 5.5V over the temperature range of -40°C to +85°C.
