Marvell

More and more, people are committed to find impactful ways to conserve energy in their homes and businesses. And yet simple solutions, such as LED lighting, have been cost-prohibitive, and thus out of reach for the mainstream consumer. With Marvell's single-chip, unique mixed-signal LED driver architecture, lighting designers can more easily build energy-efficient, superior lighting features and controls into lower cost mainstream professional and consumer products, enabling more widespread adoption of eco-friendly LED lighting.

88EM8080/88EM8081

Marvell's 88EM8080 and 88EM8081 are first-generation AC/DC LED driver chips from 8080 family. The 88EM8080 operates at a 60kHz switching frequency while 88EM8081 operates at a 120khz switching frequency. Based on Marvell's unique mixed-signal architecture and patented digital PFC technology, the 8080 family delivers industry leading performance in high power factor (> 0.99), low total harmonics distortion (< 10%), and high efficiency (up to 90%), as well as precise LED current control while operating over universal voltage inputs from 85VAC to 305VAC. Using the single-stage fly-back topology, the 8080/8081 reduces system BOM cost and space, enabling a range of mass consumer applications such as retrofit LED bulbs where cost and space are constrained.

Target Applications:

• A lamps
• PAR lamps
• Down lights, recessed lights
• Troffer lights, panel lights
• Outdoor lights

A19 LED Reference Bulbs

Marvell provides manufacturing-ready designs for 40W incandescent replacement LED light bulbs. Designs include electrical, mechanical, thermal and optics elements. The designs are ready for Energy Star® (with exception of beaming angle), Lighting Facts, EMI/EMC, CE and UL safety requirements, allowing quick time-to-market for LED lighting OEMs and ODMs. The design package includes driver, mechanical design files, and test reports for thermal, colorimetric and electrical performance measurements.

• Cree: The Cree A19 reference LED bulb uses the 88EM8081 with Cree XLamp XP-E HEW LEDs to offer high-efficiency, high power factor, and low BOM cost for cost-sensitive, space-constrained, and high-temperature operated retrofit bulb applications.
• Lumileds: The Lumileds A19 reference LED bulb uses the 88EM8081 with Lumileds Luxeon A LEDs to offer high efficiency, high power factor, and low BOM cost for cost-sensitive, space-constrained, and high-temperature operated retrofit bulb applications.
