Single-stage controller IC drives and dims 12V retrofit lamps
Based on NXP’s GreenChip technology, the SSL3401 generates a stable current while dimming down to below 5% of maximum light output in most common practical situations. While maximum lamp power depends on the thermal design of the lamp, a typical 7W MR16 LED lamp using the SSL3401 achieves THD below 15%, power factor above 0.9, efficiency up to 78% and LED ripple current below ±10%, claims NXP.
“Energy-conscious consumers and businesses worldwide are keen to replace halogen lamps with LEDs – but making the switch to dimmable MR16 LEDs is not always as straightforward as one would expect. With the SSL3401, we’ve designed a compact single-stage controller IC specifically for dimmable MR16 LED lamps, and tested it extensively for compatibility with a wide range of dimmers and transformers,” said Ryan Zahn, general manager, lighting solutions product line, NXP Semiconductors. “By helping retrofit lamp manufacturers to reduce costs, we also hope to ease the transition from halogen to LED on a broader scale, particularly as 12V MR16 lamps emerge as a popular choice in both commercial and residential lighting.”
Evaluation samples are available now, with volume production starting in July 2013.
