NXP Semiconductors' SSL2129A is a highly efficient GreenChip controller IC for compact, deep-dimmable LED retrofit lamps from 4 W to 25 W. The SSL2129A offers a best-in-class dimming performance measured in compatibility per watt, for a single-stage mainstream LED driver application. The SSL2129A is suitable for use in isolated and nonisolated compact LED driver topologies, delivering excellent efficiency at a reduced system cost.

The SSL4120T is a highly efficient LED power supply solution for designs ranging from 75 W to 400 W. It integrates a power factor correction (PFC) controller and a controller for an LLC resonant half-bridge converter (HBC) for powers up to 400 W. The maximum PFC frequency of 380 kHz enables compliance with THD regulations.
