产品信息
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).
