SANTA CLARA, Calif., April 24, 2013 /PRNewswire/ --Marvell (Nasdaq: MRVL)
today announced that MSi LED Lighting has selected the Marvell^® 88EM8183 deep
dimming single-stage AC/DC LED driver integrated circuit (IC) to power its new
line of LED bulbs they are manufacturing for 3M. MSi selected Marvell's
88EM8183 LED driver because of its high compatibility with a wide variety of
installed dimmers, deep dimming performance similar to that of incandescent
bulbs and the lowest component count on the market. Leveraging Marvell's
driver, 3M is unveiling the industry's leading dimmer compatible LED bulbs for
distribution at major retailers nationwide.


"Today's consumers demand low-cost, residential LED lighting with advanced
dimming capabilities. Together with MSi and 3M, we are not only meeting this
demand, but furthering the mass market adoption of LED solutions," said
Kishore Manghnani, vice president of Green Technology Products at Marvell. "We
are pleased MSi and 3M have chosen Marvell for their LED bulbs. Marvell's
highly integrated 88EM8183 LED driver helps MSi deliver high-performance,
affordable LED bulbs in multiple form factors for 3M at leading U.S.

Marvell's highly integrated LED driver drastically reduces the bill of
materials (BOM), enabling MSi to distribute cost-efficient and
high-performance 3M LED bulbs in retailers nationwide. Marvell's 88EM8183
driver significantly improves performance of the bulb to achieve smooth, deep
dimming down to 1 percent of current, compared to competitive solutions that
are only capable of dimming down to 10 to 20 percent of current. Additionally,
the 88EM8183 IC is compatible with many different types of (TRIAC) wall box
dimmers from a wide variety of global manufacturers.

"To meet the needs of consumers, it was essential that we evaluated several
vendors based on their ability to support a variety of installed dimmers at
the price point we desired," said William Weiss with MSi."Marvell's 88EM8183
LED driver was the best choice for our bulbs because of its performance,
affordability and overall quality. By lowering the component count by nearly
half, Marvell's driver significantly lowers the bill of materials, helping our
team distribute bulbs at a lower price to end users. Marvell's solution also
hosts the greatest level of integration, allowing our team to deliver
different bulb form factors to consumers across the nation."

Features of the Marvell 88EM8183

Marvell's 88EM8183 IC:

  oImplements advanced dimming control algorithms to comply with the National
    Electrical Manufacturers Association Solid State Lighting 6 (NEMA SSL 6)
    dimming standard.
  oEmploys 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.
  oIntegrates a high-voltage start-up circuit to supply energy to the chip
    during power-up, eliminating an external field-effect transistor (FET) and
    associated power circuits.
  oMonitors 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.
  oDelivers up to 90 percent efficiency, a power factor above 0.95 and lower
    than 20 percent total harmonics distortion via unique design techniques,
    enabling lighting OEMs and ODMs to exceed ENERGY STAR requirements.
  oSupports both fly-back and buck-boost topologies for isolated and
    non-isolated bulbs.
