IS31FL3224
DESCRIPTION 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 40m A, 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 for channels 3×n+2, n=0~7, for example: one group for R is CS0, CS3, CS6 … CS21. one group for G is CS1, CS4, CS7 … CS22 and one group for B is CS2, CS5, CS8 … CS23). Proprietary algorithms are used in IS31FL3224 to minimize power bus noise caused by passive ponents on the power bus such as MLCC decoupling capacitor. All registers can be programmed via HSB (high speed series bus, up to 10MHz), DSB (Manchester encoded, daisy chained serial bus, up to 2MHz), SPI (12MHz) bus or I2C (1MHz) interface. IS31FL3224 can be turned off with minimum current consumption by...
