Cree A19 LED Platform Brief

Marvell A19 LED Reference Bulb with Cree LEDs
Turn-key Design for 60W Dimmable Incandescent Replacement
LED Lamp
PRODUCT OVERVIEW
Marvell®/Cree® A19 LED Reference Bulb is a reference design for a 60W dimmable incandescent replacement LED light
bulb suitable for high volume, low cost production. It uses Marvell’s deep dimming, single-stage AC-DC LED driver
IC, along with Cree® XLamp® XB-D LEDs, to offer high quality light, high efficiency, high power factor and low BOM
cost for cost sensitive, space constrained and high temperature operated retrofit bulb applications. The bulb supports
ENERGYSTAR® Omnidirectional intensity light distribution and provides the industry’s best dimmer compatibility with
the vast majority of dimmers on the market. The complete package includes driver design files, mechanical design files,
optical source files, and test reports. It also ships with interchangeable clear and frosted bulb covers to show different
styles of illumination.
