1 / 36 page ![]() This is information on a product in full production. February 2013 Doc ID 023464 Rev 5 1/36 36 HVLED807PF Offline LED driver with primary-sensing and high power factor up to 7 W Datasheet − production data Features ■ High power factor capability (> 0.9) ■ 800 V, avalanche rugged internal 11 Ω power MOSFET ■ Internal high-voltage startup ■ Primary sensing regulation (PSR) ■ +/- 5% accuracy on constant LED output current ■ Quasi-resonant (QR) operation ■ Optocoupler not needed ■ Open or short LED string management ■ Automatic self supply Applications ■ AC-DC LED driver bulb replacement lamps up to 7 W, with high power factor ■ AC-DC LED drivers up to 7 W Description The HVLED807PF 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). Table 1.
