LED controller IC for mains operated retrofit lamps offers higher dimming performance

NXP Semiconductors N.V. has announced LED controller IC for compact, deep-dimmable LED retrofit lamps from 4 to 25 W. The SSL2129A features 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.”

Availability: The SSL2129A compact, deep-dimmable controller IC for LED lighting is now in volume production with product samples available immediately.
