Chinese manufacturers gathers together the AC/DC and DC/DC

"In recent years, zte, huawei and a large number of domestic terminal system manufacturers in mobile phone and consumer electronics field has made great progress, the domestic IC manufacturers in this market, but also capture territory to have made a lot of share, in addition to domestic customers, other than in the international brands such as samsung, LG, MOTO, Nokia's ODM/OEM cooperation manufacturers in the scheme has also easily can see domestic products, for example, China resources silicon power some single product, a month out to a customer can reach 7-8 million a, not replace, but the sole supplier. Obviously, such as huarun silicon micro market sales deputy general manager FangGuoTeng mentioned, is Chinese manufacturers in the mobile phone and the rise of consumer electronics market made the market AD/DC or DC/DC manufacturers. FangGuoTeng believe that Chinese manufacturers not only catching the opportunity, but also created some new market. For example, before some low order but a large quantity of products with RCC scheme, now due to low load power requirements more stringent, lower production cost of labor, and integration to promote the reliability optimization, with IC to replace has also is a direction, it makes certain market immediately expanded several times.

Hangzhou ShiLan micro WuJianXing argues that: in the AC/DC applications, 65 w the small and medium-sized power external power adapter, China IC manufacturers already with high quality and low price products occupy a large amount of market share. And in more than 65 w in high power applications or the internal power, because the cost is not sensitive to IC, or to Europe, America, Japan and other international brand companies scheme is given priority to. China's IC manufacturers to obtain further breakthrough, first of all to further improve the product itself each technical performance indicators, in addition, still need to continue to improve quality control ability, meet the customer's tough top quality requirements. ShiLan micro current AC/DC major products for the 65 w the following applications is given priority to, according to the output power and the application field is divided into three different block: 5 w - 24 w output power, mainly used in DVD/DVB power panel, standby power supply and portable product adapter; 3 w - 6 w output power, the original edge control, mainly used in mobile phone charger; 0 w - 65 w power output, the power section is mainly used in notebook, printer adapter, LCD MONITOR and small size LCD TV, the second half of this year will have two product to the market.

Core friends microelectronic products mainly is focused on the AC/DC and DC/DC and plasma TV display driver. "In the alternative process we basically has the following characteristics: quality performance quite guarantee our customers to use safety, price keep steadily reduce guarantee the customer long-term interests, supply adequate, timely service to ensure customer stable production. LiZhiHong says, core friends main foundry is on China and huahong, the technology that USES a voltage range 5 v - 800 v multiple voltage; Line width from 0.35 microns to 1 micron multiple levels.

Fai mans microelectronics co., LTD., marketing director ZhuZhiZhang think that conforms to the international energy saving standard AC/DC is a kind of new opportunities. In the AC/DC power chip as an example, the domestic some outstanding IC design company has been able to design to meet the latest international energy conservation standards such as 30 mw standby power consumption of the power control IC, and with its excellent price began to take most of the mobile phone charger market at home and abroad. The company focus on the AC/DC integrated power solutions, on behalf of the products are FT831D, this is the one which can realize output constant current/constant pressure function of the primary side feedback control chip, the constant current precision is less than 5%, constant pressure precision is less than 10%, can easily meet the requirements of authentication USB charger tell, meet the energy star 2.0 requirements. The updated version FT835 realized on the basis of less than 30 mw standby loss, can meet the five mobile manufacturers make the no-load loss five-star standard.

However, different from the AC/DC, DC/DC, especially in the industrial application, or some people called the Broad Market Market, at present or international brand factory such as countries half, beauty letter, LingLiEr characteristic and the German's, are topped situation. Chinese firms in the market operation have difficulty, because different from vertical market, these products or the main system original design also is in foreign, or that every single case quantity can is too small, difficult to cause the domestic startups interest, and sometimes traditional IDM factory with their own unique technology in opt-in subscribers who have adjusting product, the baffle plate is relatively high. "However, the direction of the development potential of the domestic market resources for local manufacturers chances will be a lot better than Taiwan manufacturer, supplier in Taiwan in the past focused on PC market, for domestic booming industrial electronics, mostly by selecting target market and development instead of foreign products as direction, and local manufacturers in addition, also has more close to the market advantage. That FangGuoTeng analysis.

LED drive innovation competition

Compared with AC/DC, due to the LED lighting and big size backlight is in recent years in emerging markets, and technology in the rapid evolution, this let Chinese IC manufacturers see technological innovation opportunity, they said this field, we are with the international companies have not too far away.

"At home and abroad and LED lighting technology development is very rapid, market competition is very fierce. Overall, foreign manufacturers because of strong power management technology background and market background, LED lighting technology in a leading level. But, the LED lighting is a new field of application of IC manufacturers in China and Europe and the United States, enter the time gap is not big, you basically have similar starting point and opportunity. From the release of new products to see, performance indicators are equal. The ShiLan WuJianXing think. Relative to the mature industry, customers are also more willing to in the emerging field (such as LED lighting, etc.) using a new brand, so for the new brand products has brought more market opportunities. "We have every reason to look forward to China's IC enterprises in LED lighting field of good performance. He said with confidence.

ShiLan micro are early into the LED driver design company, one of the main application field for LED lighting, has now formed a complete LED lighting solutions. According to different power supply, the product is divided into two parts: DC/DC LED drive, mainly used in MR16, MR11, street light/panel light/fluorescent lamp of the secondary constant current; AC/DC LED drive, at present the main application field there is high pressure to shoot the light (E27 / GU10), ball steep light, PAR lamp, fluorescent lamp, panel lights and street lamp, etc.

And FangGuoTeng, said, in LED lighting, China resources silicon neville's PT4115 almost is the industry standard chip MR16 application, monthly supply millions of stars, product marketing all over the world more than ten countries, including the United States, day, Korea, method, means, Russia, Spain and other Asia and other regions, "but also because of the target clear and in the face of great domestic and foreign competitors to follow, in order to avoid losing jiangshan, the price decline rapidly." To PT4115 as the foundation, silicon wei has also developed other various chip, covered all kinds of lamps and lanterns type and size power such as T5 / members &people waiting fluorescent lamp, PAR lamp, ball steep light, corn lights and street lamp to wait, also sum up the isolation and the isolation scheme.

He said, China resources power for silicon into relatively early, thus to have the "early bird" advantage, at present and foreign manufacturers comparison from shipments, it should be have an advantage, and from the technical accumulation and evolution perspective, is also the same, "we will continue to strengthen the investment product optimization to increase efficiency, high PFC, no flicker thyristor dimmer, system simplified as to input electrolytic capacitor, such as strengthen the integration to reduce the size of the chip, and spend a lot of system engineer of resources to provide a EMI and radiation plan." A year ago, they began to the foreign traditional lamps and lanterns companies provide project, and has also get a few big manufacturers use. Local LED power supply IC has to enter the international market.

The general manager HuXiaoBo into microelectronics, said their innovation in high level of integration. "We will power control as much resistance capacity and semiconductor device integrated into internal IC, IC peripheral devices needed to reduce, reduce the power cost, especially when we design the front feedback voltage regulator and constant current IC, further satisfy the power terminal customer's cost reduction requirement, the power of miniaturization and a step forward. Because we have done with IC LED drive power small volume, high efficiency, stable work, in the LED lighting field, and into power management IC has been a lot of use." He explained.

With the above several different, can is red semiconductor innovation concerned with large and medium size LED backlight application. Can he LvChengChang semiconductor vice President, said the company LED backlight driver IC series of products using the UMC high pressure and BCD technology, product OCP810 * series are widely used in 5 inches to 10 inch TFT - LCD screen LED backlight drive; The product OCP812 * series will be widely used in size to inch TFT - LCD screen LED backlight drive. Since the company's proprietary technology, the development of the lead in the industry, can make the cuhk tft-lcd LCD screen LED backlight system provides efficiency as high as 90%, and can provide low cost and high performance products.

LvChengChang said, the company will be in the technical aspects of innovation, such as baimiao tft-lcd LCD screen area backlight dimming technology, which is based on how fast in a particular area of the back light source part to move light respectively, or adjust the different area of the back light brightness, let the picture looks more dark or more light, regional dimming can save use the number of light sources, and makes the picture area looks more real, etc.
