GENERAL DESCRIPTION
IS32FL3209 is prised of 18 constant current channels each with independent PWM control, designed for driving LEDs, PWM frequency can be 29kHz (default) or 4kHz. The output current of each channel can be set at up to 78mA (Max.) by an external resistor and independently scaled by a factor of 1, 23/24, 22/24, 21/22, 20/24, 19/24, 18/24, 16/24, 14/24, 12/24, 11/24, 9/24 and 7/24. 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...
