BOOST structure, conversion efficiency of more than 92%, device heating low, high stability, longer service life, PCB small size, ultra-thin design. 3. Current control error ±5%, flexible and convenient current adjustment design can easily match different manufacturers and models of the screen. Design to meet EMC requirements, through CE certification. 4. The voltage is self-adaptive. The lamp string of the optical backlight module automatically adjusts the voltage. The focus of the work is on the constant current. 5. Adopt ferrosilicon aluminum magnetic ring inductor winding, higher temperature coefficient, higher magnetic saturation and higher stability.  6. Comes with current regulation function. Specification: Condition: 100% Brand New Item Type: Driver Board Material: PCB Input Voltage: 10-25V Output Voltage: 35-85V Output current: Default 100MA (can be increased to 800MA) Limit Parameters: When input at 24V: Vout = 75V Iout = 800mA or maximum 60W When input at 12V: Vout = 75V Iout = 400mA or maximum 30W Current Regulation: 30-200MA Suitable for TV/ Monitor Size: 12-24inch Size: Approx. 8.5 * 4.5cm / 3.3 * 1.8inch Weight: Approx. 20g Package List: 1 * Driver Board Notes: 1. You need to have a certain basic knowledge of physics, electronic and electrician, and you need to have a clear understanding of the core structure of liquid crystal display, LCD TV and other products. 2. Limit parameters refer to the maximum bearing capacity of the product in the process of application. Use below the limit parameters in actual use. 3. Backplane common electronic symbol code Chinese and English are as follows: A. VCC:The supply voltage is positive, the circuit supply voltage (voltage is usually12Vor24V) B. ON / OFF, ON, EN, ON_BLWait:Switching pin, switching signal pin (voltage range is usually in2.5V-5Vbetween) C. PDM, VDAJ, BL-PWMWait:Brightness adjustment feet, or called dimming feet.(Dimming will have two modes, one is the digital mode-PWM, One is analog dimming-DC.PWMCalled pulse width modulation, which produces a rectangular square wave signal, the frequency is generally200HZ-2KHZ,The magnitude of the voltage is usually3.3V, & Lt;PDIMIs the English abbreviation,DimIs the meaning of the dark meaning of the word meaning that "brightness." Analog dimming is carried out by means of a DC voltage, usually provided directly to the tuning pin0V-5VofDCVoltage to control the brightness of the purpose. ) GND: ground (power supply negative) LED +:Light - emitting diode (light bar) positive LED-:Light - emitting diode (light bar) negative The above symbols contain most of the LCD motherboard with the backlight on the code, the connection as long as the corresponding code in accordance with their respective access will not be wrong. Frequently Asked Questions Before Purchasing: Question 1: installed bright not up? 1. Check the polarity of the cable is correct? LED positive and negative are correct. 2. Measure the supply voltage to see if there is no voltage to the board, the machine boot state to measure the LED + there is no boost, generally higher than the VCC voltage. 3. If there is no boost, please measure the voltage on the ON pin, the normal voltage should be about 3.3V. 4. If the above conditions are normal, then again in the case of shutdown power to measure the LED - the resistance between the series of GND, the normal should be a small resistance, 2 ohms or less. Check the above steps are normal after the rest is only possible that the problem is the LED light bar. Question 2: machine bright, but the brightness is not enough? If the brightness is still not bright enough to measure when the PDIM pin, if the voltage has been adjusted by more than 4V need to change the voltage by other means, it will directly float the foot test What, if the brightness can meet the way by changing the pin voltage to achieve brightness requirements. If the way through the foot off the brightness is not enough to increase the brightness of the other way through. Question 1: a constant size of the TV driver board can not substitute? A: As long as the light bar working voltage of 80V or less no matter how many inches of TV, this product can be lit. Note: This is only lit, not to say that is appropriate. If you need the exact answer the best way is to provide the panel backlight module parameters (light of the operating voltage, rated current, etc.), if we can provide accurate data-like "private custom" -like service. Then again, if that can not determine the number of volt-volt light bar when the how to do it? This time there is a very simple way is
