Arrow Electronics Inc. of Melville, N.Y., has announced that it has teamed with Cree Inc. of Durham, N.C., and National Semiconductor Corp. of Santa Clara, Calif., to deliver a reference design for a flicker-free, wide-dimming-range LED driver board for a range of commercial, residential and industrial lighting applications. The new reference design, featuring white LEDs on a programmable board that meets the Energy Star power requirements, allows engineers to rapidly develop an LED lighting product, the company said. The design specifies Cree’s XLamp LED package, which has the brightness of four LEDs in a single chipset and offers added convenience and cost savings by reducing the number of LEDs and optics required. The design also includes National’s LM3445 Triac dimmable LED driver, which delivers the industry’s first flicker-free, wide 100:1 dimming range, Arrow said, while customers designing the LED driver board will receive technical expertise and support from Arrow.
