Beijing, April 25, 2013- Content Electronics Technology (Marvell, NASDAQ: MRVL), a global leader in integrated chip solutions, today announced that MSi LED lighting has adopted Marvell® 88EM8183 deep dimming single-stage AC / DC LEDs The driver integrated circuit (IC) is equipped with a new LED light bulb product line manufactured by 3M. As a meticulous choice for MSi, the Marvell 88EM8183 LED driver is highly compatible with all types of installed dimmers, has a deep dimming performance similar to incandescent bulbs, and requires the fewest components in the industry. With Marvell drivers, 3M has introduced industry-leading compatible LED light bulb dimmers, which are sold through major retailers. Kishore Manghnani, Vice President of Green Energy Products at Marvell, said: "Today's consumers need low-cost residential LED lighting with advanced dimming capabilities. Through cooperation with MSi and 3M, we not only meet this demand, but also further promote the public Market application of LED solutions. We are pleased that MSi and 3M's LED bulb products use Marvell technology. The highly integrated Marvell 88EM8183 LED driver helps MSi launch high-performance, affordable LED bulbs in a variety of appearances. Keep 3M lighting products leading the US retail market. " The highly integrated Marvell LED driver greatly reduces the bill of materials (BOM), enabling MSi to manufacture and sell highly cost-effective 3M LED bulbs. The Marvell 88EM8183 LED driver IC is designed for deep dimming that can smoothly adjust LED currents as low as 1%. Compared with similar LED driver solutions that can only achieve 10% to 20% dimming, the performance is significantly improved. In addition, the 88EM8183 IC is compatible with many different types of (TRIAC) wall dimmers from different manufacturers around the world. William Weiss of MSi said: "We have evaluated multiple vendors, focusing on the ability of each vendor's solution to support installed dimmers at a reasonable cost, which is essential to meet consumer needs. Step. Marvell 88EM8183 LED driver has become our best choice because of its performance, price and overall quality. The Marvell driver reduced the number of components required by nearly half, greatly reducing the bill of materials, and helping our team provide bulb products to end users at a lower price. Marvell's solution achieves the highest degree of integration, allowing our team to provide consumers with different specifications of light bulb products to consumers across the country. " Marvell 88EM8183 product features Marvell's 88EM8183 integrated circuit: • Adopts advanced dimming control algorithm, which meets the requirements of the National Electrical Manufacturers Association SSL 6 (NEMA SSL 6) dimming standard. • Adopts Marvell's unique primary current control method, which does not require an optocoupler and related feedback circuit, while providing very high adjustment accuracy over a wide AC input range. • Integrated high-voltage start-up circuit to supply power during power-up, eliminating the need for external field effect transistors (FETs) and related power circuits. • Can monitor the dimmer status and manage the dimmer load to maintain normal operation through the internal digital core and analog circuits, eliminating the need for external dimmer bleed circuits required by existing solutions on the market. • Through a unique design method, an efficiency of up to 90%, a power factor higher than 0.95 and a total harmonic distortion lower than 20% are achieved, so that lighting OEMs and ODMs can easily exceed the requirements of "Energy Star". • Supports flyback and buck-boost topologies for isolated and non-isolated LED lights.
