• Common Electronic symbolic code of Backlight: 

• VCC: The positive of voltage supply.Circuit supply voltage (voltage is usually 12V or 24V) 

• ON/OFF,ON,EN,ON_BL:Switch signal pin 

• PWM,PDIM,VDAJ,BL-PWM:Brightness adjusting pin 

• GND: Ground (negative electrode) 

• LED+: the positive electrode of Light emitting diode (lamp) 

• LED-: the negative electrode of Light emitting diode (lamp) 

• Application: 

• Product features: 

• 10-42 inch LED Backlight Lamp Driver Board Constant current board 

• BOOST structure 

• Conversion efficiency reached more than 92% 

• 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°C(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
