GreenChip™ Controller ICs

NXP Semiconductors' GreenChip™ controller ICs, SSL2129 and SSL4120, designed for LED lighting

NXP Semiconductors' SSL2129A is a highly efficient GreenChip™ controller IC for compact, deep-dimmable LED retrofit lamps from 4 to 25W. 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. NXP Semiconductors' SSL2129A GreenChip Controller IC
Features   Applications
  • Benchmark dimmer compatibility
  • Buck or flyback controller-only IC, (non)-isolated
    • Controller-only SSL2129A
  • High power factor >0.9
  • Dimmable retrofit LED lamps
  • Dimmable driver modules for LED lighting

The SSL4120T is a highly efficient LED power supply solution for designs ranging from 75 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. NXP Semiconductors' SSL4120T GreenChip Controller IC
