Chip makers are working hard to reduce the price of LED lighting driver ICs. As the price of LED chips has dropped rapidly, and the cost of light system thermal system is not large, the LED bulb manufacturers have turned to LED lighting driver IC manufacturers to reduce prices. In response to this trend, semiconductor companies such as NXP Chips and Infineon have begun to adjust their product development strategies to enhance cost competitiveness.
Start four strategies NXP spell LED driver IC price cuts
NXP has developed a new product strategy to quickly meet market demand for LED lighting driver ICs. Zhang Weichao, lighting product marketing manager of NXP Greater China, pointed out that the company will move to new countries by switching to new high-voltage processes, packaging plants, integrating more functions in LED lighting driver IC solutions, and The big strategy is to reduce the unit price of non-dimming LED lighting driver ICs that integrate high-voltage MOS field-effect transistors (MOSFETs) to $0.20 to $0.40 in 2013.
In fact, among the LED bulbs, the unit price of the high-voltage MOSFET is second only to the LED illumination driver IC. Zhang Weichao emphasized that the price of high-voltage MOSFETs has reached 0.1~0.2 US dollars. Therefore, the price of high-integration LED lighting driver ICs has dropped to 0.2~0.4 US dollars, which is extremely difficult. Therefore, it is necessary to adopt a new product strategy to achieve This goal.
Improve product strength Infineon highlights cost-effective advantages
Different from NXP's active reduction of the price of LED lighting driver ICs, Infineon faced the price reduction of LED lighting driver ICs, and chose to help customers reduce the overall bill of materials (BOM) costs by improving the overall cost performance of LED lighting solutions.
Xie Dongzhe, marketing manager of Infineon, Taiwan, pointed out that the commercialization of lighting technology will undergo three stages of introduction, mass infiltration and differentiation. Nowadays, the LED industry has gradually entered a large number of adoption periods, and cost and efficiency have become the two most important factors for terminal consumer procurement. Great consideration.
As the LED lighting market enters a stage of high adoption, Infineon will continue to provide customers with better cost and performance options in LED lighting solutions such as lighting driver ICs, MOSFETs and microcontrollers (MCUs) to reduce BOM costs. Purpose, and performance is competitive in the market.
In the face of the next differentiation period, the company will provide platformized power solutions to customers, with cost, performance and functional design flexibility, to help customers face the ever-changing LED lighting applications, card general lighting and benefits Base market. In addition to the cost-effectiveness of product enhancement, LED driver IC developers are also investing in the development of high-voltage MOSFET products to solve the problem of LED lighting system factory due to the high capacity of high-voltage MOSFETs, resulting in deferred shipments, while winning the favor of important customers.
High-voltage MOS out-of-stock chip makers push for high integration solutions
Wang Yongbin said that in 2013, the LED lighting market will be more vigorously developed. However, due to the serious shortage of high-voltage MOSFETs, the developers of LED lighting systems are caught in the predicament of having many orders but unable to ship, and it is difficult to make a big push in the market.
In order to avoid the market expansion due to insufficient supply of high-voltage MOSFETs, chip manufacturers including NXP, Infineon, STMicroelectronics and Baoer Inte (PI) have introduced LED lighting drivers that integrate high-voltage MOSFETs. IC solutions to ensure that customers LED lighting products are shipped flawless, while taking the opportunity to expand the market in the LED lighting driver IC market. Zhang Weichao pointed out that LED lighting driver ICs that integrate high-voltage MOSFETs must have high-voltage processes. However, due to the high threshold of high-voltage process technology, not all chip vendors have the ability to develop, so it is expected that under this wave of shortages, fear There will be a trend of LED lighting driver IC suppliers' growth and decline.
In order to aggressively insert the high-integration LED driver IC solution market, Wang Yongbin stressed that NXP has introduced the ABCD3 high-voltage process and is expected to start mass production in 2013. This process is not only more suitable for integrating high-voltage MOSFETs, but also reduces leakage current while eliminating LED lighting. Applying unnecessary functions, energy produces a more cost-effective LED driver IC product.
In addition to strengthening high-pressure process technology, since only a few high-voltage MOSFET manufacturers such as STMicroelectronics, Toshiba and Infineon are available at this stage, NXP has also done a good job to ensure the smooth development of high-integration solutions. Preparation for preparation.
Zhang Weichao revealed that NXP expects that the LED lighting market will expand rapidly in the second half of 2012. Therefore, it has already purchased products from high-voltage MOSFETs in advance, and now it can guarantee customers to achieve high-integration LED lighting driver IC solutions within six to eight weeks. In the future, it will be shortened to three to four weeks to pick up the goods. In addition, NXP has plans to invest in high-voltage MOSFET manufacturers to gain a more stable source of supply.
In view of the fact that LED lighting driver ICs account for a significant increase in the cost of light bulbs, semiconductor manufacturers are facing a huge cost test, so reduce the unit price of LED lighting driver ICs through product and technology strategies, while ensuring cost reduction to avoid sacrificing excessive gross margin. It is imperative. It is expected that under the price reduction of the chip makers, the proportion of LED lighting driver ICs in the bulbs will fall. 
Strive for LED lighting driver IC price reduction chip developers to strengthen cost competitiveness
Faced with increasingly stringent cost requirements for LED bulb manufacturers, driver chip developers are actively adjusting their product development strategies, such as switching to high-voltage processes to produce integrated MOSFET solutions, or enhancing drive functional integration to reduce unit price and shrink material The purpose of the list cost.
