Renesas’ winning combination digital addressable lighting interface (DALI) design is becoming more and more popular for home and building lighting applications. The standard enables simple wiring and options to change configurations. The DALI 2.0 standard allows users to control up to 65 individual lights and/or 32 groups of lights. Complex color light scenes of multiple luminaires can now easily be set up through DALI. For this reference design, energy efficiency LEDs are used, often arranged in stripes. For ambient lighting, RGB is preferred, but for general lighting, warm/cold white light is needed.
Renesas offers a highly integrated, complete solution for driving five LED stripes for red, green, blue, and warm/cold white lights with up 70 V and 700 mA each, resulting in 245 W of total LED power. The 70 V are internally boosted out of the 24 VDC input.
Renesas’ Synergy S128 microcontroller (MCU) already contains a dedicated peripheral for DALI 2.0 so the total BOM is further reduced. Renesas also provides a power solution to run the system out of the standard 24 VDC.
