Nomination Title: Marvell LED Lighting – 88EM8183

Tell the story about this nominated product or service (up to 525 words). Describe its function, features, benefits, and performance to date:

Today’s consumers are looking to be greener. From recycling their bottles and cans to turning down the AC during the night – our society understands the need to do its part and be ecologically friendly. There is one market, however, that has traditionally been slower to gain consumer approval. The transition from incandescent to LED bulbs has been taxing for consumers. Energy-efficient lighting has not seen mainstream adoption due to the perceived high price of the bulbs and limitations on current-day technology.

But that is changing.
                               
Leveraging Marvell®’s unique mixed-signal architecture and advanced dimming control technology, the highly integrated 88EM8183 LED driver IC is designed to achieve smooth deep dimming down to one percent. This is a significant performance improvement compared to competitive LED driver solutions that only achieve 10- to 20 percent dimming, which the human eye does not perceive as a significant drop in light level. The 88EM8183 IC reduces the number of components needed for LED drivers by more than half, dramatically shrinking needed board space, allowing original equipment manufacturers (OEMs) and original device manufacturers  (ODMs) to bring LED lighting to all kinds of lamp form-factors, including A19, PAR, BR, GU10 and Candle, without compromising dimming performance.

Marvell’s 88EM8183 LED driver provides a cost-efficient solution that allows OEMs and ODMs to enable dimming capabilities in LED bulbs. Supporting universal AC input and a wide range of LED output wattages from a few watts up to 100 watts, the 88EM8183 decreases design efforts and improves operational efficiency by taking a product platform approach. This approach reduces the number of LED lamp SKUs and streamlines inventory management.

The 88EM8183 IC also is designed to be compatible with more than 150 different types of (TRIAC) wall box dimmers from various manufacturers around the world, providing consumers with the same out-of-the box dimming experience with new LED bulbs that they’re accustomed to with incandescent bulbs.

Marvell’s 88EM8183 Driver IC:

• Implements advanced dimming control algorithms to comply with the National Electrical Manufacturers Association Solid State Lighting 6 (NEMA SSL 6) dimming standard.
• Employs Marvell’s unique primary side current control method, which eliminates the need for an opto-coupler and associated feedback circuit while delivering high regulation accuracy over wide range AC input.
• Integrates a high voltage start-up circuit to supply power to the chip during power up, eliminating an external field-effect transistor (FET) and associated power circuits.
• Monitors dimmer status and manages dimmer load to maintain proper operations through the internal digital core and analog circuit, eliminating external dimmer bleeder circuits required by existing solutions on the market.
• Delivers up to 90 percent efficiency, power factor above 0.95 and lower than 20 percent total harmonics distortion via unique design techniques, enabling lighting OEMs and ODMs to easily exceed ENERGY STAR requirements.
• Supports both fly-back and buck-boost topologies for isolated and non-isolated bulbs
