Using the TLC5929, 16-Channel LED Driver with 7-Bit
Global Brightness Control, Power-Save Mode, and Full
The Texas Instruments TLC5929 evaluation module (EVM) is a fully assembled and tested circuit for
evaluating the TLC5929, a 16-channel, constant-current LED driver with 7-Bit Global Brightness Control,
Power-Save Mode, and Full Self-Diagnosis for LEDs. The EVM is capable of driving up to 50 mA per
channel when powered from a 5-V supply.

  • Page 4: Connector And Test Point Descriptions

    Serial Connector (J2) Evaluation of the series connection of several TLC5929 is possible with this EVM. Connect J1 of the second EVM with the serial connector, J2, of the first EVM. The signals BLANK (pin 7), SCLK (pin 9), LAT (pin 8), and GND (pin 6) of the first EVM are directly connected to the second EVM.
