TLC59116ITPWRQ1

LED照明驱动器 Automotive 16-Channel FM+ I2C-Bus Constant-Current LED Sink Driver 28-TSSOP -40 to 105

Description

The TLC59116-Q1 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%.

Features
