HVLED807PF
Offline LED driver with primary-sensing and high power factor up to 7 W
LED照明驱动器 Off-Line LED 800V 11Ohm 0.9 High Volt
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 lowvoltage 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).
Features HVLED807PF
■ 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 HVLED807PF
■ AC-DC LED driver bulb replacement lamps up
to 7 W, with high power factor
■ AC-DC LED drivers up to 7 W
