Enter the LED lighting market power plant IC reference design firms

In view of light emitting diode (LED) lighting factory is numerous, and many small and medium enterprises, coupled with the system design is not mature, so many technical challenges, A Morimi (On Semiconductor), STMicroelectronics (ST), TI (TI) and national semiconductor (NS) chip etc. through the design of high performance companies competing to reference and speed to market, to attract customers.

A Morimi computing and consumer electronics technology marketing manager, said Lin Zhiyan, only the actual understanding of the specifications required by customers, in order to design a reference design in line with customer expectations.

Lin Zhiyan said that most of the LED lighting business, because the power system integration ability is insufficient, so the component suppliers rely on a higher degree. If the supplier can provide a reference design for the needs of different lamps, will help customers to shorten the product development process, and the production of cost-effective LED lamps. At this stage, the company has been able to provide customer base MR16, PAR30 and other four to six kinds of bulb reference design, the future will continue to launch ten to sixteen kinds of bulb reference design.

Not only A Morimi, STMicroelectronics, TI, national semiconductor LED lighting power supply and drive chip operators also have published LED bulb reference design diversity, show the semiconductor industry Great minds think alike. Lin Zhiyan stressed that although many vendors have launched LED chip reference design all kinds of lighting, it can meet the customers for the electromagnetic interference of high profit and high price, (EMI) and other requirements, and truly achieve the purpose of speed to market still has difference.

Following the early 2011 acquisition of SANYO semiconductor (SANYO Semiconductor), A Morimi to obtain non isolated LED chip product line and technology driven, Lin Zhiyan pointed out that the United States and its future isolated Anson and non isolated LED driver chip product line will be more complete, to meet customer needs in different application areas.

According to the development trend of LED lighting chip isolated and non isolated forest drive, Zhiyan analysis, design of the metal cooling LED lighting system, requiring agencies or electrical isolation reached; once changed to ceramic cooling system architecture, especially from 5 to 7 watts of small power, limited volume, cost constraints, non isolated collocation scheme it will become a trend, and for different application requirements, the future of non isolated step-up, step-down and hybrid architecture will be in the market according to a party.

Compared with LED backlight TV (LED TV) LED lighting market, the high degree of customization, Lin Zhiyan believes that the development of TV LED than the LED lighting industry has been gradually mature, so the development of a unified standard, and LED lighting customization high proportion, the semiconductor industry must be more flexibility in the design and supply of products to meet market demand.
