SN3218 18 Channel LED Driver

SN3218 is comprised of 18 constant current channels each with independent PWM control, designed for driving LEDs. The output current of each channel can be set at up to 23mA (Max.) by an external resistor. The average LED current of each channel can be changed in 256 steps by changing the PWM duty c.
