10-42 inch LED Backlight Lamp Driver Board current boardBOOST structureConversion efficiency reached more than 92%low heat of the Device, stability,have a longer service lifethe PCB is small,Slim design,Current control error within 5%You can use the 12V supply to reduce the system cost This product is current board, voltage is automatically adaptedThe temperature rise is controlled at about 25degrees (Temperature rise = device surface temperature - ambient temperature)Limit parameters:When to 24V input: Vout = 75V Vout = 720mA maximum or 60WWhen to 12V input: Vout = 75V Iout = 400mA maximum or 30W1. VCC: The positive of voltage supply, Circuit supply voltage (voltage is usually 12V or 24V)2. ON/OFF,ON,EN,ON_BL: Switch signal pin3. PWM,PDIM,VDAJ,-PWM: Brightness adjusting pin4. GND: Ground (negative electrode)5. LED+: the positive electrode of Light emitting diode (lamp)6. LED-: the negative electrode of Light emitting diode (lamp)Colour:As shownMaterial:PC+MetalPackage Contents:5 x LED LCD TV Backlight Current BoardOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
