  • TLC5946: TLC 5946 lacks a few signals. Can we run it?

    Resolved
    Part Number: TLC5946 I'm trying to run the LED using the TLC 5946. In my controller, There is a lack of signal for TLC 5946. SIN, SCLK, XLAT, BLANK, but the signal is coming out. GSCLK, no MODE signal. Do you need the circuits you need to get out? I wonder…

  • Project design using TLC5946

    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…

  • How to set the voltage of TLC5946's out pin?

    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…

  • TLC5946 only accepts 10 LEDs

    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…
