16 Channel LED Driver Evaluation Module
This product has been released to the market and is available for purchase. For some products, newer alternatives may be available.
The TLC59116F is an I2C bus-controlled, 16-channel LED driver that is optimized for red/green/blue/amber (RGBA) color mixing and backlight application for amusement products. 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%. 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 190 Hz and an adjustable frequency between 24 Hz 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. This EVM helps the user evaluate the features of the Texas Instruments TLC59116F, which is an I2C™ bus-controlled, 16-channel LED driver. The user’s guide includes setup instructions, a schematic diagram, a bill of materials, printed-circuit board layout drawings, and software instructions.
