Along with the progress of the LED light chip LED power supply technology, the growing, increasingly high brightness LED power supply, its application is becoming more widely. Instructions from the early instrument into the large LCD screen backlighting, flashlights, car directions, lighting, decorative lighting, etc., until the general lighting field, such as table lamps, bedside lamps, fluorescent lamps and street lamps.
LED power supply technology advances in recent years mainly in the high-efficiency, high power, high voltage technically. In the field of mobile phones and other portable, mainly because the white 100w led driver applications, low-voltage differential drive, the charge pump drive are developed for these applications-driven approach, low dropout 100w led driver differential pressure has done is very low (50mV/20mA), the charge pump drive is now 2 times, 1.5 times and 1.33 times, the goal is to improve efficiency, increase the range of voltage applications. The company introduced the industry's first innovative drive a total of Yin and Yang LED low dropout driver chips will soon be launched simultaneously drive common cathode and common anode LED charge pump driver IC alleged that the chip can only automatically adjust the external capacitor voltage to achieve 1X to 2X, thus greatly improving the efficiency of the LED.
