Other Parts Discussed in Thread: TLC5940 Hi,
We are looking for PWM controller IC like TLC5940.Please confirm that the device(TLC5940) meet following requirements
1.Each PWM channel must be able to withstand the application of at least 36VDC.
2.Each PWM…
Other Parts Discussed in Thread: TLC5940 I have a question regarding the design of an application with TLC5940 chips. Main question When designing LED applications with TLC5940 drivers (with seperate LED supply and VCC for the TLC); would one use capacitors…
Part Number: TLC5940 I'm looking to use the TLC5940 to drive a 9W 12V RGB LED. While 12V supply itself would not require the MOSFETs in this design, I would like to use them to offload heat.
The LED needs around 250 mA per color channel, too much…
Hello Daniel, Yes, the registers can be programmed without blanking the LEDs. Some example projects set the blank pin high during device programming, which is probably what you are referring to. Best Regards, Casey
Other Parts Discussed in Thread: TLC5951 , TLC5940 Hello E2E,
I am working with a customer who has done a lot of prototyping using the TLC5940. They have code working for that chip from an arduino. However, they actually need to use 8 RGB leds so they are…
Other Parts Discussed in Thread: TLC5940 hello, I'm daisy-chaining 10 tlc5940 drivers.
I've calculated the required iref value to be 2.2k ohm.
right now I'm using 10 resistors. each driver has its own resistor.
I was wondering: is it possible…

Other Parts Discussed in Thread: TLC5940 We currently have an application where five TLC5940 chips are cascaded for a total of 80 channels of control. The chips are driven by a Teensy 3.1 microcontroller using hardware SPI. A series of 160 distinct patterns…
Other Parts Discussed in Thread: TLC5940 Hi!
I've designed a board with 6 daisy-chained TLC5940 and 5 of them are working perfectly, but the second chip in the chain does not. When i connect the power supply the leds connected to the second one lights…
