To establish a new benchmark NXP LED driver

NXP semiconductors (NXP Semiconductors) announced today that its power LED driver solution series of products has three major advances: SSL2101 LED driver IC successfully completed the accelerated life test, to convince the markets LED the service life of the product can reach longer; launch for SSL LED lamps and the module of the new product SSL2102, this product is also integrated electric light function; released for online design tool of SSL application, greatly facilitate the customers by the engineer NXP four product design of LED lighting products, improve the progress of design and development.

NXP semiconductor lighting products market and business development director Jacques Le Berre said: "10 times the energy efficiency is expected to reach LED lighting incandescent lamp, according to the manufacturer's report, LED lamp life can be more than 50 thousand hours. The reliability of key electronic components, especially LED drives IC, is critical to the overall reliability of LED lighting products. Our ongoing accelerated life test has been more than 7000 hours, with the test results will be more optimistic. At present this result has established a new benchmark for the industry, and prove the NXP LED electricity IC based driver has the ability to support long life lamps. In addition, our latest SSL2102 products and online design tools can help innovative lighting companies to accelerate the pace of product development and accelerate the popularity of LED lamps in the general lighting market. "

Life test of LED driver IC

NXP is an industry run time LED IC the longest drive accelerated life test, the test since December 2008, running to zero fault. As of now, the test run time is 7000 hours and continue to prove, NXP LED driver IC power based on LED products fully meet the requirement for a long life. The traditional life test program of the semiconductor industry benchmark for usually in 1000 hours, the test time, NXP test went beyond this standard.

Accelerated life testing is mainly for NXP issued earlier this year, the industry's first integrated dimmable mains LED driver IC SSL2101. NXP from standard products were randomly selected from a batch of SSL2101 IC driver should be tested in high stress conditions, after all the test samples in 150 ~ C IC node temperature more than 7000 hours of operation remained functional complete. NXP adopted a number of tests with different settings to detect all possible failure modes in several situations, including continuous open, open / close the switching cycle and various combination. According to the life acceleration model, the estimated lifetime of SSL2101 in real lighting applications is estimated as follows:

105 ~ C under the condition of life more than 60 thousand hours at 115 C under the conditions of life more than 35 thousand hours at 125 C under the conditions of life more than 20 thousand hours at 150 C under the conditions of life more than 7000 hours as onchi en Chi Pu special assessment part of its latest LED driver IC the actual life of the project. Continuous operation reliability method used in the testing, will continue to the end of life of natural products.

The latest LED integrated power dimming drive IC supports 25W maximum power

SSL2102 is the newest member of NXP lighting products series, its depth dimming capability can be as low as 1% light intensity, and is compatible with a variety of dimmer. This compact, highly integrated, high energy efficient LED driver IC is a new breakthrough in compact LED lighting, is the ideal choice for small enclosures sealed LED lighting applications.

SSL2102 is suitable for high efficiency and high power factor LED lighting applications, including: 8W to compact 15W application; 15W to LED module of 25W, such as LED used in the spotlight and the lamp; and the maximum power of up to 25W store counter display LED lamp string.

The main features of SSL2102 include:

Realization of natural light control by means of built in logarithmic dimming curve

Support most dimmer in the market (such as SCR, transistor)

High integration, very few external components required

Design of switching power supply supporting isolated and non isolated architecture

A SO20 wide body package with enhanced heat dissipation

Best energy efficiency Valley switch detection

Built in magnetic detection

Built in thermal protection (OTP)

Support from the LED driver IC rectifier voltage start as an integrated dimming controller and switching power supply module, SSL2102 and SSL2101 in the same function, but the support power is higher, so that customers will be able to design a design applied to the power rating of a wider range of different final products.

SSL application online design tools

LED driver IC SSL application online design tool NXP latest release allows the engineer to easily test NXP products, NXP this series of four products, these four products are used in the new SSL2102 and SSL2101 dimmable products, as well as for non adjustable optical products SSL1522 and SSL1523.
