Marvell External LED Driver Reference Designs For High Quality, Cost-Effective Commercial LED Lighting PRODUCT OVERVIEW Marvell® offers a family of turn-key external LED driver solutions providing manufacturing-ready designs for low cost, high quality commercial LED lighting that include options to integrate smart lighting control functionality. The solutions include driver designs optimized for downlights, panel lights and other luminaries in the 12-40W range. These designs are ready for EMI/EMC and CE/UL safety requirements, allowing quick time to market for LED lighting OEMs/ODMs. (DFKUHIHUHQFHGHVLJQNLWLQFOXGHVDQ/('GULYHUERDUG4XLFN6WDUW*XLGH8VHU0DQXDOGHVLJQ¿OHVWUDQVIRUPHU VSHFL¿FDWLRQDQGWHVWUHSRUWV These external LED drivers feature 0-10V dimming capability that is compatible with wall box dimmers available in North American, European and Asian markets. The driver and dimming circuit conform to UL Class 1 and Class 2. This dimming circuit can be bypassed for use in a non-dimmable applications. Applications that require Smart LED Lighting control, including on/off switching, dimming, color mixing or color correlation temperature (CCT) tuning, can also be developed with the addition of DALI or ZigBee® communication modules which allows networked lighting control. Most of the Marvell external LED driver boards (see table below) include an interface to accept these smart communication modules making it easy to integrate this functionality into lighting designs. ,IUHTXLUHGUHIHUHQFH¿[WXUHVZLWK/('OLJKWVPD\DOVREHRUGHUHGZLWKWKH/('GULYHUUHIHUHQFHGHVLJQ7KHSRVVLEOH ordering options are listed below.
