power behind vibrant solid-state lighting
NXP's high-power AC/DC converter reference design enables fast proof-of-concept single-color applications. It's fully tested solution based robust components proven technologies that simplifies design solid-state lighting (SSL) luminaires.
benefits Efficient power conversion from mains Maximize energy efficiency minimize form factor through reduced heat generation Accurately controlled current through LEDs Meets regulations Isolated safety Power Factor Correction above dimming through current control applications Decorative lighting Commercial lighting e.g. freezer lights Cove lighting White spotlights Other lighting applications Connecting directly mains, AC/DC converter reference design high-power strings distributes power local distributed light engines. Optimized driving high-power LEDs series (giving total VF(LED) approximately easily adapted different voltage and/or current requirements. reference design supports dimming through current reduction, example, logarithmic variable resistor (potentiometer). This allows dimming less than achieved. offers wide range fly-back converters suited applications from GreenChipSwitched Mode Power Supply (SMPS) control family. demonstration board based this reference design uses NXP's TEA1530, which offers efficient fly-back converter concept power requirements above
