IS31FL3246 Datasheet | Lumissil

36-CHANNEL LED DRIVER GENERAL DESCRIPTION IS31FL3246 is prised 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 set at up to 25mA (Max.), all channels are grouped as G group(OUT1, OUT4, OUT7...), R group (OUT2, OUT5, OUT8...) , B group (OUT3, OUT6, OUT9...) and each group has a 8 bits output current control register which allows fine tuning the current for rich global RGB color mixing.
