Dialog tests the MR16 dimming solid-state lighting market with an innovative LED driver

     Dialog is the fastest growing supplier of mixed-signal semiconductor integrated circuits in Europe, adopting such a fabless business model, from the past seven years data can be seen, Dialog's performance growth is very rapid, in 2007 when the annual receivable is only 87 million US dollars. By 2014, which was also just announced some time ago, the revenue has reached more than 1.1 billion.

     Dialog has about 1,400 employees worldwide, and more than 70% of them are engineers involved in research and development. Dialog is also very focused on some major applications in power-saving technology. In this regard, it includes several large areas, including power management, and ultra-low power audio technology. At the same time, it is also very concerned about the emerging development of the Internet of Things, so it has also launched many short-distance wireless transmission technologies. One of the most important technologies is called Bluetooth intelligence, and at present, solutions have been launched for Bluetooth intelligence.

     The last piece is also very important, that is, the power conversion of ICBC, which applies some LED applications in solid lighting. Which is now very hot Bluetooth smart, in the international market has now launched a solution, this solution is the smallest volume, the lowest power consumption of a solution, compared with other competitor products, the volume is less than half more than him, power consumption is equivalent to half of the competitors.

     Mark Tyndall, Senior Vice President of Corporate Development and Strategy and general manager of Dialog's Emerging Products Business group, said: "In the Chinese market, Dialog has launched a lot of applications on Bluetooth intelligence, one of the most important successful cases is the cooperation with Xiaomi, Xiaomi has just launched their smart bracelet, which uses Dialog technology." In addition, in the recent new product launch conference also repeatedly mentioned such a few cases, mainly in power management, with leading domestic smartphone manufacturers, including LG mobile phones, Meizu, and Lenovo smartphones have selected Dialog technology."

     Since the acquisition of iWatt, it has achieved a market-leading position in dimmable LED applications, providing the world's leading dimmable low-power LED ics. In 2014, 100 million units were sold in the Chinese market. Dialog has the most comprehensive product portfolio in LED drivers, and the only one that may not have been involved before is low-voltage LED drivers.

     Scott Brown, Senior Director of Marketing, Dialog's Power Conversion Business Group: "As we all know, most of the MR16 lamps are low-voltage lamps, to use low-voltage to use the transformer inside, generally the power supply line inside 120V or 220V voltage to 12V AC, but for low-power LED, the general voltage can not reach such a 12V, Therefore, it is difficult for current LED products to be compatible with existing transformers.

     Another LED challenge, is its dimmability, this dimmability is generally in the traditional dimming with thyristor dimmer, this dimmer in the market a wide variety, in the past many years Dialog has been in this area has a leading position, the use of Dialog data algorithm, can achieve a very excellent dimming performance. In addition, the lamps made by Dialog are consumer products first, and consumer goods are generally consumers who are very sensitive to costs, so it is also a big challenge in terms of cost reduction.

     The third challenge is that the LED products used by consumers are not the same, some consumers use low pressure LED, and some use high pressure COD sky system, Dialog released MR16 dimming LED driver can be compatible with both products. One is the iW3688, which offers the highest dimming performance and best dimmer compatibility. Another platform is the iW3662LED driver, which is Dialog's first drive into the MR16 market, and is currently the only LED driver on the market that can be reduced to 4V, which is that it is able to beat the competition in terms of transformer, dimmer compatibility and overall cost."
