Other Parts Discussed in Thread: TLC5946 1: I need a board to control 14 channels of LEDs. And the brightness of each channel need to be adjustable seprately. So I chose TLC5946, is it a good choise?
2: If use TLC5946, Can I use I2C or UART or other common…
Other Parts Discussed in Thread: TLC5946 The datasheet of TLC5946 said that max voltage of out0~out15 is 17V. But there is no detail information about how to control this voltage.
Now i connect a LED string to channel 8. But the max voltage of out8 which…
Part Number: LP5891 Other Parts Discussed in Thread: , TLC6948 , TLC6946 , TLC6984 , LP5890 , TLC6983 , TLC5943 , TLC5946 , TLC5948A , TLC5940 , TLC59401 , TLC5929 Hi,
Can the LP5891EVM be connected to external LED display(chips)?
Best Regards,

Hi!
When I send static PWM data to the IC, all leds light up in the respective brightness. But when I regularly change the data (animations, fading etc), only every 2nd led lights up and the lighting LEDs are pretty dim. When I only send 10 pwm data words…
Part Number: TLC5955 Other Parts Discussed in Thread: LP5891 , TLC6983 , TLC6984 , TLC5946 , LP5890 Hello,
Simple question heres. 1. Because GSCLK requires a constant 33MHz signal. Can I just supply a 33MHz oscillator as the input here? 2. If a short or open…
Dear TI 5946 expert,
Sorry to say but the databsheet I do not understand well. question:
In figure12 the outputs are going on (low) after the DC data clocked in (XLAT rising edge). My 5946 IC shows no any output. Other part of the documentation mentions…
Other Parts Discussed in Thread: TLC5946 Hi,
This is what we do:
1) MCU Init
2) Send DC setting to driver (the value is 63). at oscilloscope signals seems correct
3) Send GS settings to driver (the value is 4032). at oscilloscope signals seems correct …
Thanks for the information Hardy! We decided to go with the 40mA TLC5946 instead. We are using two of them. Thanks for clarifying how the shift register interface could work.
Part Number: TLC5947 Other Parts Discussed in Thread: TLC5946 Hi there,
I am powering 24 LEDs that all require less than 20mA of current. I am also wanting to power 5 LEDs that require 50mA of current. I am looking at the TLC5947 (readily available library…
Other Parts Discussed in Thread: TLC5946 , TLC5943 I'm having issues with a TLC5946.
What I originally did, is
SCLK, SIN, XLAT, MODE and XHALF connected to MCU
GSCLK connected to independent oscillator (30MHz)
BLANK not used / set to 0
So, what I…
