Keywords:LED? lamp driver? PSR? HVLED805?

STMicroelectronics rolls out the HVLED805, a family of mains-operated LED lamp drivers for more efficient LED retrofit lamps featuring primary-side current regulation (PSR).

The HVLED805 PSR controller integrates high-voltage startup for efficient power-on and the 800V power metalCoxideCsemiconductor field-effect transistor allows a reduction of the snubber network. It has a quasi-resonant operating mode that saves energy for LED lighting and reduces the EMI filtering required.

PSR maintains the consistent LED current needed to ensure consistent light output, without requiring the current-sensing components and optocoupler. The HVLED805 claims five percent accuracy of LED current regulation using PSR.

The HVLED805 is in mass production in the SO-16N narrow package, priced at $0.70 in quantities of 10,000. Alternative pricing options are available for larger quantities.
