Off-line LED driver with primary-sensing and high power factor up to 15W

The HVLED815PF device is a high voltage primary switcher intended for operating directly from the rectified mains with minimum external parts and enabling high power factor (> 0.90) to provide an efficient, compact and cost effective solution for LED driving. It combines a high-performance low voltage PWM controller chip and an 800 V, avalanche rugged Power MOSFET, in the same package. There is no need for the optocoupler thanks to the patented primary sensing regulation (PSR) technique. The device assures protection against LED string fault (open or short).

Key Features

  • High power factor capability (> 0.9)
  • 800 V, avalanche rugged internal 6 Ω Power MOSFET
  • Internal high voltage startup
  • Primary sensing regulation (PSR)
  • ± 3% accuracy on constant LED output current
  • Quasi-resonant (QR) operation
  • Optocoupler not needed
  • Open or short LED string management
  • Automatic self supply
