Sipex white LED driver aimed at China's camera mobile phone market

Since its inception location provides high performance power management device and interface device and optical storage device of Sipex company, the increase of Chinese market support, not only increase the number of China offices set up and Application Support Engineer, and according to the market and sell products application characteristics, early and good for product line China market map.

"Next generation mobile phone selling point is the built-in camera flash, built-in camera flash is expected next year listing the essential function of China mobile phone." Sipex China Marketing Director Qiu Gengyuan said. Aiming at the next hot demand Chinese mobile phone market, Sipex company has locked the camera flash driver, LED driver, boost / buck regulator and LDO regulator power management device further seize the market. Recently, Sipex launched a series of solutions of white LED camera flash. Among them, the buck / boost charging pump SP6686 is said to be the smallest solution for mobile phones with white LED camera flash. The device can provide the maximum current is 400mA, the output current can be adjusted and selected for flash and continuous lighting mode respectively; IC input voltage range of 2.7V to 5.5V, depending on the battery input voltage can be automatically converted to 2x from linear mode buck boost mode, to ensure that the forward voltage distribution does not depend on the current LED. Another 700mA non inductive white LED camera flash driver SP6685 has a small footprint, providing two independent adjustable output current can be used for flash and lighting mode.

With mobile phone function more and more strong and other portable products display size increases, they continue to demand the miniaturization of products at the same time, the power consumption is increased continuously, which will lead to the power management device toward miniaturization, high efficiency, energy saving direction. For example, the efficiency of the SP6656 400mA Sipex synchronous buck regulator can reach 98%; the PowerBlox series of high current, high voltage and ultra small peripheral circuit elements DC/DC SP7651 buck regulator needs fewer dimensions of only 7 x 4mm. In order to facilitate the user to use, Sipex also announced the website PowerBlox Lab and LED Lab application tools, according to the application needs to provide a complete reference circuit diagram and BOM, or even the cost of BOM.

About half of the share Sipex interface device products business, including RS232, RS422, RS485, USB and multi protocol transceiver, data signal transmission between the electronic system or the internal network, and to ensure that, between the computer and digital peripheral devices and portable devices on a wired connection. The trend of development, on the interface of the device that Qiu Gengyuan, RS232, RS422, RS485 and other traditional single protocol serial interface device will still have room to grow with steady demand, they are the interface devices widely used, but the manufacturers in order to bring products to the international market, to support multi protocol serial interface devices demand is gradually warming up.

For this application, Sipex launched a data rate up to 20Mbps eight channel monolithic multi protocol transceiver SP3508. The working voltage of SP3508 is only 3V, but its TTL I/O can produce LVTTL signal level, and can produce 5.5V voltage to support the output voltage swing required by serial communication standard. SP3508 is also compatible with V3.5, V.11, NET1/NET2 standards, TBR2 standards. It is understood that China's demand for multi protocol transceiver is not large, but with the Chinese products to the international market, multi protocol transceiver market potential in China still can not be ignored. In this regard, Qiu Gengyuan stressed that Sipex will work together with customers to find a market selling point in order to enliven the market demand, and the introduction of practical products to achieve win-win situation with customers.

Perhaps it is precisely based on this idea, Sipex optical disk storage technology and services to provide support for the development of the next generation DVD burner core components such as laser pickup head for the CD-ROM Research Center, Tsinghua University. China hopes to catch up with the international trend in the next generation of DVD core components development. If these products can get up in China, which is also a big growth point Sipex". Qiu Gengyuan said. According to reports, Sipex optical memory devices include optical detection IC, laser diode driver and advanced power control IC, which accounted for 25% of the global market share of light detection IC.

Currently Chinese business accounted for about Sipex's global business 20% - 25%. But Qiu Gengyuan believes that the Sipex product positioning in the end, the price and performance is very suitable for the main application characteristics of China products, with product characteristics, Sipex, fast delivery and ability to grasp market, this figure is expected to have a lot of room to grow.
