产品概述
描述
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 an optocoupler thanks to the patented primary sensing regulation (PSR) technique. The device ensures protection against LED string fault (open or short).
