Most of the driving power of the blue-ray LED applications in its use in the production of transformers, inductors, electrical parameters of the requirements of ten high demand precise takes a lot of manpower and financial resources in order to achieve the cost of industrial production is difficult to decline further. Innovation and optimization of the chip algorithm so that the led high bay lights output current accuracy is not sensitive to the periphery of transformers, inductors and other electrical parameters, and reduce the manufacturing costs of the inductors, transformers and LED the whole lamp.
BP310X this innovation to optimize the chip algorithm, the application circuit is very simple, few parts around, in line with the concept of low cost, and industrial production. Figure 3 is a typical application circuit, the main stage side of the constant current, the secondary feedback circuit is no longer an obstacle on the power supply size and cost a great convenience, so that the power supply volume to the most demanding occasions, such as Bulb, GU10 spotlights. Traditional optocoupler feedback structure there is the aging of the optocoupler and very safety test within the Light Bulb 60-90 º C ambient temperature, the reliability issues become the focus of attention of the manufacturers and customers. The main stage side of the constant current technology matures, innovation-driven power chip algorithm, the design of new technologies, making the application circuit to become insensitive to certain difficult quality control parameters of transformers and inductors, blue-ray LED applications power and lighting manufacturers that can facilitate improve product performance and lower costs is a win-win choice.
