SANTA CLARA, Calif., Oct. 24, 2012 /PRNewswire/ --Marvell (Nasdaq: MRVL)
today announced the availability of a new turnkey reference design developed
with Cree, Inc. for 60-watt equivalent dimmable A19 LED bulbs, continuing the
two companies' ongoing collaboration to drive the LED lighting revolution. The
new ENERGY STAR® compliant design – integrating Marvell's latest deep dimming
driver IC, the 88EM8183, and Cree's leading edge XLamp^® XB-D LED – further
enables the mass adoption of LED lighting with a consumer-friendly replacement
bulb that is completely compatible with existing lighting infrastructure. The
new reference design allows for smooth, flicker-free deep dimming, and offers
high efficiency, high power factor and omnidirectional light distribution
meeting ENERGY STAR guidelines. The reference design will be on display at
Hong Kong LIGHTFAIR from Oct. 27 – 30.


"Marvell's ongoing collaboration with Cree is addressing major barriers to
consumer LED adoption – specifically, light quality, dimming capabilities,
dimmer compatibility and cost. Working together, Marvell and Cree provide
incomparable LED solutions, bringing high performing and efficient lamps with
advanced capabilities to market through complete reference designs primed for
high-volume, low-cost production," said Lance Zheng, Senior Technical
Marketing Manager for the Green Technology Products Group at Marvell
Semiconductor, Inc. "This new joint A19 reference design, featuring Marvell's
88EM8183 driver IC, further advances energy-efficient lighting for consumers
while ensuring deep dimming and full compatibility with existing lighting

"Cree and Marvell share a common goal – to drive the LED lighting revolution
by improving everybody's experience of solid state lighting," said Mike
Watson, Senior Director of Marketing, LED components, at Cree. "Cree's XLamp®
XB-D LED based on our SC^3 technology platform, doubles the lumens per dollar
with a smaller footprint, increased efficiency and improved light extraction.
Combined with Marvell's innovative driver technology, this joint project
demonstrates an original, high performing, cost effective LED replacement

About 88EM8183 LED driver IC
Leveraging Marvell's unique mixed-signal architecture and advanced dimming
control technology, the highly integrated 88EM8183 LED driver IC is designed
to achieve smooth, flicker-free deep dimming. The 88EM8183 is compatible with
the vast majority of wall box (TRIAC) dimmers – leading edge, trailing edge
and digital dimmers – from manufacturers around the world providing consumers
an out-of-the-box dimming experience. Additionally, the 88EM8183 IC
significantly reduces the number of components needed for LED drivers,
dramatically shrinking needed board space, allowing OEMs and ODMs to bring LED
lighting to a wide array of lamp form-factors, including A19, PAR, BR and
GU10, without compromising dimming performance.

Marvell and Cree have built copies of the 60-watt design to support North
American, European and Asian power infrastructures. These newly manufactured
reference designs are available immediately and will be on display at Cree's
booth, #IE-B22, at Hong Kong LIGHTFAIR, being held Oct. 27 – 30 at the Hong
Kong Convention and Exhibition Center. A 75-watt model of the reference design
is expected to be available soon.
