LED LCD Universal TV Backlight Constant Current Backlight Lamp Driver Board Boost Step Up Module 10.8-24V to 15-80V 14-37 Inch
Description: 
1.14-37 inch LED Backlight Lamp Driver Board Constant current board 
2.BOOST structure,Conversion efficiency reached more than 92%  
3.Low heat of the Device, stability,have a longer service life 
4.The PCB is small,Slim design,Current control error within ± 5%  
5.This product is constant current board, voltage is automatically adapted 
 
Specifications:
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)
The temperature rise is controlled at about 25degrees (Temperature rise = device surface temperature - ambient temperature)
 
Limit parameters:
When to 24V input: Vout = 75V Iout= 720mA maximum or 60W
When to 12V input: Vout = 75V Iout = 400mA maximum or 30W
You can use the 12V power supply to reduce the system cost
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.
PCB size: about 6.80*3.0cm/2.68"*1.18"
 
Note: 
Size for manual measurement, there may be a 0 to 2 cm error, belongs to the normal phenomenon. 
And due to the difference between different monitors, the picture may not reflect the actual color of the item. Thank you! 
Package Included:
