Recently, Power Integrations (hereafter referred to as PI) introduced two single-stage power factor correction LED driver ICs for solid-state lighting (SSL) applications that support TRIAC dimming. They are LinkSwitch-PH and LinkSwitch-PL, both of which enable flicker-free, single-chip TRIAC dimming that achieves similar illumination to incandescent lamps. In order to learn more about these two ICs, Optoelectronics News Network interviewed Bill Weiss, PI's US business development manager, at the Guangzhou International Lighting Exhibition and PI booth.
Pay attention to the LED lighting market and carefully cultivate customers
Bill said that PI's 2009 turnover was $216 million, and in the first quarter of 2010 it reached $71.5 million. With a 20% market share in the global offline LED lighting industry, PI places great emphasis on the LED lighting market.
Traditional incandescent and fluorescent lighting technologies are concentrated in a few companies. The market is controlled by several large companies, but PI realizes that the LED lighting market is composed of many small companies, especially in China, many companies are Do LED lamps. The first reason is that the LED industry has just begun to rise. It is not necessary to invest too much to start LED lighting. Although it takes a huge investment to make LED chips, there are only a few companies with such large scales, but LED lighting companies. Much. This constitutes a very different LED market than the traditional lighting market. PI must reach out to all these small LED lamp production companies to make them interested in PI products, so that there are many opportunities to open up the PI product market. The LED lighting market is very important to PI, so PI will invest a lot of resources to develop technology, develop new products, and put new products into the market. Because China's market is different, people feel that it is the world's largest place to produce LED lights, PI has established a sound sales team and technical support team in the Chinese market, and PI also has a group of distributors, agents to help The ability to reach more customer groups is also very good.

Because there are many small companies, making technical support more difficult, PI mainly relies on training sales personnel and distributors to let them understand the characteristics and principles of products so that they can better serve customers. PI has produced a lot of detailed technical reference design materials to allow customers to read and learn on their own, so that they can make such products themselves, even if they are willing to modify the products. PI provides online design support to help designers design transformers, how to design switching power supplies, etc., which is very helpful for designers to simplify the design process. PI also offers online universities to allow customers to start learning from the most basic design for free, and to release new content every quarter. In order to speed up the listing of LED lighting products, PI also provides a practical and practical reference design.

Single-stage power factor correction LED driver IC for low cost and high reliability
LinkSwitch-PH and LinkSwitch-PL precision constant current output and high efficiency, and compatible with traditional thyristor dimmers and electronic controllers, can achieve no flash, more than 1000:1 single-phase wide dimming range and monochrome Dimming. With primary side control and single stage power factor correction (PFC), the optocoupler with low reliability at high temperature and input electrolytic capacitor can be omitted in the circuit. This design reduces the BOM cost and increases the lifetime and reliability. Sex.
LinkSwitch-PH is suitable for designing isolated power supplies with an output power range of 6.5 – 50 W. LinkSwitch-PL is suitable for designing non-isolated power supplies with an output power range of 1.5 – 16 W.
In addition, the two LED driver ICs feature a monolithic design that integrates the controller and high-voltage MOSFETs onto a single die. In summary, PI's LED lighting application uses 13 fewer electronic components than conventional secondary-side dimming solutions, which allows the LED driver power supply to be reduced in size and easily fit into the housing of conventional lighting fixtures.
PI's LED lighting drive solution uses active power factor correction (PFC) with a power factor (PF) > 0.9 to meet global energy efficiency specifications such as the European IEC, US Energy Star solid-state lighting.
