IS31FL3246 is comprised of 36 constant current channels, each channel can be pulse width modulated (PWM) by total 8 bits+10 bits (261890 steps) for smooth LED brightness control or color mixing control, 8 bits PWM (LFP) operate at 127Hz (can be disabled), 10 bits (HFP) operate at 32kHz, to minimize the audible noise. The output current of each channel can be.
2.7V to 5.5V supply
Pin to Pin with IS31FL3236A/IS31FL3237
(QFN-44, 5mm×5mm)
I2C with register address automatic increment
