Lumissil IS31FL3762: 24xn (n=2~12) configurable matrix LED driver
Programmable matrix LED driver with selectable I2C or SPI interface and 312kHz PWM frequency
General purpose 24xn(n=12~2) LED Matrix driver with selectable I2C (1MHz) or SPI (12MHz) bus interface. Each LED can be individually dimmed with 12-bit/8+4-bit/8-bit/6+2-bit PWM dither data and each LED can have an 8 bit current adjustment for precise RGB LED color mixing or smooth LED fade control. Advanced noise reduction features include 180-degree LED group phase shift, a high 312kHz PWM frequency to reduce audible noise and power ripple as well as spread spectrum technology to reduce electromagnetic interference (EMI) noise.
