Lead-free packaging Product Description NU507 is a simple high-voltage constant current element in the application of LED lighting products is very easy to use, especially in automotive electronics and AC voltage is directly driven applications, the advantages of low cost and highly efficient energy. NU507 which has excellent load and power modulation error rate and minimum output current, make LED current stability limit within a set range, a substantial increase LED life. In addition to supporting a wide range of power supply to provide power without additional outside, NU507 the VDD pin can serve as output enable (OE) function to use, with digital PWM control circuit can be used in gray-scale current control. NU507 supports digital energy technology unique series of LED drive technology, without the need to convert the power supply voltage, direct and efficient drive more stars in series of LED. This tandem drive technology to maintain high conduction angle of the sine wave and high power efficiency. When the supply voltage rises, the voltage will increase by converting electrical energy into light energy. At the same time and having a simple circuit structure and high power factor advantages. In the case requires only a small number of SMD resistors and capacitors, significantly improve product reliability and simplify production procedures. This unique multi-stage cascade driven architecture patent applications. NU507 is a high-voltage linear power supply components, will not produce electromagnetic interference, its built-in thermal protection, when more than 125 ℃ will start the output current is reduced, and closed at about 160 ℃. Also the output current is set by an external resistor, the maximum current output 80mA. Shenzhen integrity Technology Co., Ltd.
