STMicroelectronics HVLED807/15 Offline LED Drivers
STMicroelectronics HVLED807/15 Offline LED Drivers are high-voltage primary switchers that are 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. They combine 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. They assure protection against LED string fault (open or short).
