OR:  

The NXP SSL21084T is a high-efficiency driver IC with an integrated 600 V MOSFET for superior dimmable LED lighting solutions that typically operates in the lamp power range up to 15 W. The straightforward design produces a cost-effective yet compact application, suitable for use with GU10 and PAR16 formats. A low-cost bipolar bleeder circuit supports a best-in-class dimmer compatibility performance for mainstream, single-stage LED driver applications.

Features and benefits

  • Superb mains-dimmable LED driver solution (both leading and trailing edge phase cut dimmers)
  • Buck driver with integrated 600 V MOSFET
  • Power-efficient boundary conduction mode
  • Start-up JFET
  • High power factor (>0.9)
  • Full range of internal protections
  • Compatible with wall switches with built-in indication light during standby
  • Benchmark dimmer compatibility per watt
  • Compact, single-stage LED driver solution lowers eBOM cost
  • Optimized, high-efficiency operation improves total lumen output per watt, lowering energy consumption further

Applications

  • Dimmable retrofit LED lamps
  • Dimmable driver modules for LED lighting
