HVLED807PF Off-line led driver with primary-sensing and high power factor
The HVLED807PF is a high-voltage primary switcher intended to operate 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 assures protection against LED string fault (open or short).
