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 of…
Part Number: TLC5940 I developed an HW based on TLC5940 which is connected to a µC. It was for 3 days on a permanent test and it worked without any problem. The signal level was also ok at the start of the test. 3 Day later, out of 27 boards, 3 are…
Part Number: TLC5940 Hi!
The TLC5940 is power by a 5V domain for VCC and the BLANK signal have a pull-up to 5V.
To prevent random channel turn-on, BLANK should be pulled high firstly. For this reason I have a pull-up to the 5V.
The LED:s are powered by…
