TLC5960 Vadj Pin dimming is 0.12V 10%~1.0V 100% per CH current output 12~100mA
OSD brightness currently sets 0~100 steps
, 0~45 steps, 8CH backlight is normal
8CH backlight is normal at 66~100 steps
Backlighting will be Flashing from 46th to 66th
Especially in the 46~49 order, the most severe after a few seconds, some groups will shut down.
I measured the output voltage of 8 sets of Switching mos G1~G8 from 2.1V to 2.5V. The points at which Shutdown occurred are 2.1V or 2.2V.
I tried to adjust the PWM frequency 6KHZ and 260HZ, and the oscilloscope measured the 45~66 order waveform is also very stable.
I cross-tested that the Lightbar is normal, and the Flashing shut down point occurs with the low voltage of the Gate-Source.830-C5960-A11A.pdf
