Part Number: TLC5940 Tool/software: Hello experts,
I am using chip to drive the LED's. I was analyzing an issue in my program and noticed that GSCLK is not held low when driving the BLANK signal.
I would like to understand the behavior on what would…
Part Number: TLC5940 Tool/software: Hello,
I asked a question in the following thread about the issue of LEDs not lighting up properly. I asked you if the th4 and tsu4 constraints were a factor in the LEDs not lighting up properly. What I would like…

Dear TI-Team,
for my LED circuit I have 122 LEDs individually addressable by using 8 TLC5940 (RHBR). With an IRef sink current ist set to 100mA for each LED.
Whats the right voltage to power LEDs and have as few power left…
Part Number: TLC5940 Hallo,
I have made a designed base on a daisy chain of 15 TLC5940.
The project is working since about 1 years whitout problem. But today when I power on the board, it happens that one LED was on and the remainder was off which…
Part Number: TLC5940 Hi,
My customer want to make a solution of LED driver, but the boost voltage is 200V, current sink is 200mA per channel, 8-channel in total.
Can I use TLC5940 and tie two channels together to generate 200mA current sink, and use…
Part Number: TLC5940 We are using TLC5940 for PWM output, but now out0 - out 15 doesn`t have PWM output,we are using pin BLANK,DCPRG,XLAT,SIN,GSCLK. After upload program to chip, we test output pin with oscilloscope, chip will become heat, the voltage…
