Part Number: TLC5973 Dear Team,
I am redesigning a board. I need to control RGB led using my microcontroller.
The current board contains WS2811M from world semi. This IC is very difficult to get from most of our vendors.
I decided to go with TLC5973.…
Part Number: TLC5973 I have integrated the TLC5973 into a design, a section of the schematic is shown below:
There are 11 of these ICs in a chain.
When I attempt to program the devices, the data successfully cascades through the chain of devices, and…
Part Number: TLC5973 Hi,
I have a non-repetitive problem with one of the outputs.
Normally, the device configures the outputs correctly with the value written in SDI.
But sometimes one of the outputs latches up in an open state so the led is always lighting…

We are experiencing the exact same problem as described in this post. https://e2e.ti.com/support/power-management-group/power-management/f/power-management-forum/957582/tlc5973-about-emc-test
Several peaks at multiples of ±12MHz.…
Part Number: TLC5973 Hi,Ti team:
we use TLC5973 to driver RGB LED,we design a FPC which length about 700mm.We total use 8 pcs TLC5973 in the FPC.all of them driver 4 series and 8 parallel LED,The driver circuit is 20mA and the VLED is set 14.4V,The schematic…
Part Number: TLC5973 Hi TI experts,
It was applied to landscape lighting application using TLC5973. Many LED drivers are connected in series with the TLC5973's SDI->SDO solution as shown below.
If one TLC5973 fails, the LED driver connected after…
Part Number: TLC5973 Hi
Please help let me know the following questions
1. Is the execution method of PWM as described in "Figure 13. PWM Operation", If yes, what is the highest refresh rate?
2. Please provide information about Command (12bits…
Part Number: TLC5973 Hi there
Is anyone aware of any example driver code for TLC5973 RGB LED driver IC which uses TI Easyset interface. Seems like a popular application (RGB LED strings) and I'm surprised I can't find anything out there for use with this…
Part Number: TLC5973 Other Parts Discussed in Thread: LP8556 Hi,
I am planning to use TLC5973 LED current sink driver for backlight application.
My LED backlight operating voltage specs are 29V at 50mA. So, I am planning to connect backlight anode to…
