IS31FL3235A - Lumissil

IS31FL3235A 28 CHANNELS LED DRIVER

IS31FL3235A is comprised of 28 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.
