CA-6109 10-65inch LED LCD TV universal boost constant current board full bridge drive backlight high voltage board
10-65 inch LED LCD TV universal boost constant current board full bridge drive backlight high voltage board
Output Vol: 8-165v
1) The power input voltage is 10V-28V; the boost ratio is 1:7.5, 12V can be increased to 80V, and 24V boosted to 160V.
2) The LED lamp current is 248mA by default and can be adjusted to 600mA by shorting on the board solder joint.
3) The total power output is limited to 40W or less.
4) Transformer efficiency at the best operating temperature 85°C, temperature rise 30°C at 40W
5) In the reverse dimming mode, ADJ is the dimming port, the grounding is the brightest, and the high voltage is dimmed to extinguish.
6) Do not allow ADJ to float. If it is not connected, connect it directly to ground.
(1, boot plus a soft start protection, so the dimming port should be connected to the ground when not in use, it is not recommended to be suspended and not connected. 2, the setting of the dimming port is 0 ~ 3v, 0v brightest, in 2~2.5v is very dark, and it is almost protected near 3v, and 0v) is output at this time.
7) Connect VCC, GND, EN (enable) and ADJ dimming according to the sign on the board when testing. There are four input ports, the output connection is connected to the LED positive and negative output ports
