Marvell (Nasdaq: MRVL), a leader in global integrated silicon solutions, today announced the introduction of the Marvell® 88EM8187 LED controller integrated circuit (IC) family. The controllers are phase-cut, deep dimming, single-stage AC/DC constant current controllers for dimmable LED lights and luminaires. Developed on the industry-leading 88EM8183, the driver IC family features a unique mixed-signal architecture with advanced digital algorithms. The 88EM8187 product line offers unparalleled performance and is fully compatible with more than 250 dimmers worldwide, with depth dimming as low as 1% without flicker. This product line extends lamp life due to its excellent temperature regulation and 90% power efficiency.
The 88EM8187 product line also significantly reduces the number of required electronic components, reducing the overall cost of the solution. Marvell teamed up with lighting control leader Lutron to test the pre-release version of the IC. The test results show that the 88EM8187 has unparalleled dimming performance. The 88EM8187 is also part of the Marvell IoT Smart Home Lighting portfolio, which provides a total solution for interconnected smart lighting applications. Marvell has begun sampling 88EM8187 to major LED lighting OEMs and ODMs worldwide. Marvell customers are expected to deliver 88EM8187 based products this year.
Philip Poulidis, vice president and general manager of the IoT business unit at Marvell, said: "The 88EM8187 has improved performance standards across the industry, and consumers now have access to true incandescent lighting experiences, including superior dimming performance and LED energy efficiency. Even the best IC solutions of the same type require light bulb manufacturers to make some compromises when developing products. For example, manufacturers may need to limit the number of wall-mounted dimmers that are compatible with their LED lights, sacrificing dimming performance. To avoid flicker or shimmer and to exchange high component reliability for high reliability or high efficiency. The Marvell 88EM8187 does not. The 88EM8187 and its unique digital architecture provide excellent compatibility, reliability, efficiency, deep dimming and It requires very few components to deliver the best performance in the industry at the lowest system cost, so OEMs no longer have to compromise on hardware design."
Mark Jenner, director of Lutron's new business alliance, said: "We have partnered with Marvell to implement a high-performance, cost-effective dimmable LED driver solution that helps address the current compatibility issues of LEDs and dimmers. And provide a superior customer experience. For example, Marvell's new 88EM8187 works with any of our C•L dimmers to provide superior tune from one lamp to all rated loads of the dimmer. The light experience does not create shimmer, flicker, or interfere with other dimmers. These reliable solutions enhance consumer confidence and help them use more energy-efficient LED lights everywhere in their home."
Marvell and Lutron Electronics
Marvell has worked with Lutron Electronics to confirm the dimming compatibility between the pre-release versions of the 88EM8187 reference design and various Lutron LED lighting control solutions. The Lutron LED Center of Excellence provides a service for the lighting industry to test the compatibility of LED lights with Lutron C•L series dimmers. This series of dimmers is designed for LED lamps using industry-leading C•L technology, but is also listed by UL as suitable for incandescent, halogen and CFL lamps.
Key benefits of the Marvell 88EM8187 driver IC product line include:
• Excellent dimming performance
– 100% compatible with a wide range of dimmers worldwide, including leading edge, trailing edge and special (smart) dimmers;
– No flicker, low shimmer, deep dimming as low as 1%.
• Reduced system billing costs with fewer and smaller components in EMI/Vibration/Dimmer stage control circuits:
– Reduced cost by up to 25% compared to similar single-stage drive solutions.
• Integrated temperature negative feedback and optimized dimmer latching and hold current management:
– Eliminate heat in power components or “hot spots†and significantly improve reliability;
– No need for potting, further reducing costs.
• The drive has the highest electrical performance:
– >0.95 Power Factor
– drive efficiency is up to 90%;
– Provides the industry's best linearity adjustment (< 2%) over a wide AC voltage range;
– Power factor > 0.95.
• There are two packages to choose from:
– SOIC-8: Cut-only phase angle function, pin compatible with the first generation 88EM8183 chip;
– SOIC-14: Only the phase angle function is cut to achieve a single layer PCB.
