HVLED815PF LED照明驱动器

HVLED815PF

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

LED照明驱动器 Off-Line LED 800V 6Ohm 0.9 High Volt

Description  

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 highperformance  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).
