GreenChip-based Drivers for LED Retrofit Lamps Achieve Best-in-Class Dimmer Compatibility per Watt
PRWeb

NXP Semiconductors N.V. (NASDAQ: NXPI) today announced the SSL2129A - a highly efficient GreenChip(TM) controller IC for compact, deep-dimmable LED retrofit lamps from 4 to 25 W. The SSL2129A offers best-in-class dimming performance measured in compatibility per watt, for a single-stage mainstream LED driver application. Its straightforward approach also allows the application to remain compact (GU10/PAR16) and highly cost-effective, with a high power factor (PF) of more than 0.9. The SSL2129A is designed for use with an external MOSFET and can be configured in both buck (non-isolated) and flyback (isolated) topologies, for 100-120V and 230V mains supply voltages.

"Our latest GreenChip LED controller IC sets a new benchmark in dimmer compatibility. In testing and measuring 'compatibility per watt,' we've taken into account the importance of dimmable LED performance at lower input power levels, as well as many other factors," said Richard Langezaal, product marketing manager, lighting solutions, NXP Semiconductors. "By providing excellent dimming performance, high efficiency, and ease of manufacturing in a very compact form factor, the SSL2129A will help to drive down the cost of dimmable retrofit LED lamps considerably."

Evaluating Compatibility per Watt
With over 600 dimmer types sold worldwide today, nearly all of which were originally designed for incandescent lamps, designing dimmable LED lamps that perform reliably and consistently with a broad variety of dimmers remains a significant challenge for lighting manufacturers. At the same time, as LED efficacy (in terms of lumens/watt) increases steadily, the input power required for retrofit LED lamps is decreasing, raising additional challenges: Today, commercially available LED lamps need about 7 watts to replace a 40-watt incandescent bulb, and 8.7 watts to replace a 60-watt incandescent, but it is precisely under 10 watts that dimmer compatibility becomes particularly difficult.

To address this, NXP has developed a "compatibility per watt" scoring method that takes into account the absorbed mains input power, as well as a metric for compatibility determined by both stability (the ability to avoid visual disturbances such as flicker, shimmer and flashing), as well as controllability (the level to which the user can control and reduce the lamp light output, including dimming range, control span and steps in light level). Based on this parameter, the SSL2129A has demonstrated outstanding dimmer compatibility. A white paper on evaluating dimmer compatibility per watt is available from NXP.
