IS32FL3236A - Lumissil

IS32FL3236A 36-CHANNEL LED DRIVER

IS32FL3236A is comprised of 36 constant current channels each with independent PWM control, designed for driving LEDs, PWM frequency can be 3kHz or 22kHz. 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 change.
