Dialog Semiconductor Co., Ltd. is the fastest growing supplier of mixed-signal semiconductor integrated circuits in Europe. It uses a fabless-like business model. From the data of the past seven years, Dialog 's performance growth is very rapid. In 2007, the annual receivables were only $87 million. In 2014, the revenues just announced in the previous period have reached more than 1.1 billion.

Dialog has approximately 1,400 employees worldwide, and more than 70% of them are engineers involved in research and development. Dialog's main applications in power-saving technology, power-saving technology is also a very focused area, including such a large number in this area, including power management, and ultra-low-power audio technology, but also I am very concerned about the emerging development of the Internet of Things, so I have also introduced many short-range wireless transmission technologies in this section. One of the most important technologies is called Bluetooth Smart. At present, the solution has been launched for Bluetooth Smart.

The last piece is also very important, that is, the power conversion of ICBC, which applies some LED applications in solid lighting. Among them, the Bluetooth Smart, which is now very hot, has been launched in the international market. This solution is the smallest and lowest power solution. Compared with other competitors, the volume is smaller than that of other competitors. More than half of it, power consumption is equivalent to one-half of the competition.

Mark Tyndall, senior vice president of Dialog's corporate development and strategy and general manager of the emerging product group, said: "In the Chinese market, Dialog has launched a number of applications on Bluetooth intelligence. One of the most important successful cases is with Xiaomi. Cooperation, Xiaomi just launched their smart bracelet, which uses Dialog technology. In addition, in recent recent product launches, there are several cases mentioned repeatedly, mainly in power management, with domestic leading intelligence. Mobile phone manufacturers have cooperated, including LG's mobile phones, as well as Meizu, and Lenovo's smartphones have chosen Dialog technology."

Since the acquisition of iWatt, it has achieved a market leading position in dimming LED applications, providing the world's leading dimmable low power LED IC. In 2014, sales in the Chinese market reached 100 million pieces. Dialog's portfolio of LED drivers is the most comprehensive, the only one that may not have been involved before is the low-voltage LED driver.

Scott Brown, Senior Marketing Director of Dialog Power Conversion Business Group: "It is well known that most of the MR16 lamps are low-voltage lamps. To use the transformers with low voltage, the voltage of 120V or 220V inside the power supply line should be lowered. To 12V AC, but for low-power LEDs, the general voltage does not reach such a 12V, so today's LED products are difficult to be compatible with existing transformers.

Another LED challenge lies in its dimming performance. This dimming is generally used in traditional dimming. It is a thyristor dimmer. This dimmer is widely available in the market. Dialog has always been a leader in this area, using Dialog's data algorithms to achieve a very good performance of dimming. Also, because the LIGHTs made by Dialog are first of all consumer products, consumer products are generally very sensitive to cost, so it is also a big challenge in terms of cost reduction.

The third challenge is that the LED products used by consumers are different. Some consumers use low-voltage LEDs, and some use high-voltage COD in the heavenly system. The MR16 dimming LED driver released by Dialog is compatible with two. Kind of product. One is the iW3688, which has the highest dimming performance and the best dimmer compatibility. Another platform is the iW3662LED driver. This is the first time Dialog has introduced a drive in the MR16 market. It is also the only LED driver on the market that can be reduced to 4V, which is whether it is compatible with transformers, dimmers or overall cost. All of them are big ones that can open up competitors. "
