EVLHVLED815W10F, LED Lighting Development Tools HVLED815 based evaluation board: 10 W wide range high power factor isolated LED

EVLHVLED815W10F LED Driver Evaluation Board

STMicroelectronics EVLHVLED815W10F LED Driver Evaluation Board is based on a flyback topology using the STMicroelectronics HVLED815PF device. 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 (> 0.95) to provide an efficient, compact and cost effective solution for LED driving. It combines a high-performance low voltage PWM controller chip and an 800V, 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).
