IS31FL3224 Overview
IS31FL3224 is an LED driver with 24 high voltage (16V) constant current channels. Each channel can be pulse width modulated (PWM) with 7-bit/8-bit precision for smooth LED brightness control. The maximum output current of each channel is designed to be 40mA, which can be adjusted by three 7-bit/8-bit global control registers group (one group for R for CS 3×n, one group for G for channels 3×n+1, and one group for B...
