SANTA CLARA, Calif., April 15, 2013 /PRNewswire/ --Marvell (Nasdaq: MRVL)
today announced the Marvell^® 88EM8183 deep dimming single-stage AC/DC LED
driver integrated circuit (IC) will power Samsung Electronics' new suite of
LED retrofit bulbs. Announced in February 2012, the 88EM8183 LED driver IC
delivers the highest compatibility of wall dimmers, the lowest component count
in the industry and supports many of the world's lighting standards, making it
a premier solution for OEMs across the globe. Scheduled to be in retail stores
next month, Samsung's new Marvell-powered products will include A19, bulged
reflector(BR) and parabolic aluminized reflector (PAR) bulbs.


"With consumers increasingly adopting LED lighting in their homes, it is
essential that OEMs address this demand by integrating advanced dimming
capabilities into their most efficient bulbs," said Kishore Manghnani, vice
president of Green Energy Products at Marvell. "By leveraging Marvell's
88EM8183 driver, Samsung Electronics now produces high-performance, low-cost
LED bulbs that offer deep dimming capability and are fully compatible with
more than 150 different types of wall-box dimmers around the world. We believe
there is no solution on the market that provides the same widespread dimmer
compatibility and affordable price point that our LED driver IC provides."

The highly integrated Marvell 88EM8183 LED driver IC is designed to achieve
smooth, deep dimming down to 1 percent LED current, which represents
significantly improved performance when compared to competitive solutions
capable of dimming down to just 10- to 20 percent of current. The 88EM8183 IC
also is compatible with many different types of (TRIAC) wall box dimmers from
a wide variety of global manufacturers. The architecture of the 88EM8183 LED
driver IC allows a high level of integration, which greatly reduces the bill
of materials (BOM). By reducing the components count needed for an LED driver
by more than half, the Marvell solution requires dramatically less board
space, which allows OEMs and ODMs to bring LED lighting to a diverse range of
lamp form-factors, including A19, PAR and BR, without compromising dimming

Features of the Marvell 88EM8183
Marvell's 88EM8183 IC is designed to:

  oImplement advanced dimming control algorithms to comply with the National
    Electrical Manufacturers Association Solid State Lighting 6 (NEMA SSL 6)
    dimming standard.
  oEmploy 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.
  oIntegrate 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.
  oMonitor dimmer status and manage 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.
  oDeliver 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.
  oSupport both fly-back and buck-boost topologies for isolated and
    non-isolated bulbs.
