16通道FM + I2C -BUS恒流LED驱动器 16-CHANNEL Fm+ I2C-BUS CONSTANT-CURRENT LED SINK DRIVER
Description
The TLC59116 is an I2C bus controlled 16-channel LED driver that is optimized for red/green/blue/amber RGBA color mixing and backlight application. Each LED output has its own 8-bit resolution 256 steps fixed-frequency individual PWM controller that operates at 97 kHz, with a duty cycle that is adjustable from 0% to 99.6%.
