31FL3206 Overview
IS31FL3206 is prised of 12 constant current channels each with independent PWM control, designed for driving LEDs, PWM frequency can be 24kHz (default) or 3.6kHz. 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, 11/12, 9/12 and 7/12. The average LED current of each channel can be changed in 256 steps by changing the PWM duty cycle...
