IS31FL3246 Overview
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. Proprietary programmable technology is used to minimize audible noise caused by MLCC decoupling...
