Common Electronic symbolic code of Backlight:
1 VCC:The positive of voltage supply?Circuit supply voltage (voltage is usually 12V or 24V)
2 ON/OFF,ON,EN,ON_BL:Switch signal pin
3 PWM,PDIM,VDAJ,BL-PWM:Brightness adjusting pin
4 GND:Ground (negative electrode)
5 LED+:the positive electrode of Light emitting diode (lamp)
6 LED-:the negative electrode of Light emitting diode (lamp)
Application
Product features:
·14-37 inch LED Backlight Lamp Driver Board Constant current board
·BOOST structure
·Conversion efficiency reached more than 92%
·low heat of the Device?stability,have a longer service life
·the PCB is small,Slim design,Current control error within ± 5%
·You can use the 12V power supply to reduce the system cost!
·This product is constant current board, voltage is automatically adapted
·The temperature rise is controlled at about 25??Temperature rise = device surface temperature - ambient temperature?
·Limit parameters:
When to 24V input: Vout = 75V Vout = 720mA maximum or 60W
When to 12V input: Vout = 75V Iout = 400mA maximum or 30W

Warm Tip:
Limit parameter refers to the the maximum capacity when product in the application process.In fact,please under the limit parameters to ensure product reliability when using.
