TLC59108IPWR

产品概述

The TLC59108IPWR is an I²C bus controlled 8-bit LED Driver that is optimized for red/green/blue/amber (RGBA) colour mixing and backlight applications. Each LED output has its own 8-bit resolution (256 steps) fixed-frequency individual PWM controller that operates at 97kHz, with a duty cycle that is adjustable from 0 to 99.6%. The individual PWM controller allows each LED to be set to a specific brightness value. An additional 8-bit resolution (256 steps) group PWM controller has both a fixed frequency of 190Hz and an adjustable frequency between 24Hz to once every 10.73 seconds, with a duty cycle that is adjustable from 0 to 99.6%. The group PWM controller dims or blinks all LEDs with the same value. Each LED output can be off, on (no PWM control) or set at its individual PWM controller value at both individual and group PWM controller values. Four hardware address pins allow up to 14 devices on the same bus.
