EVALHVLED815W15 STMicroelectronics

EVLHVLED815W15 15 W high power factor LED driver based on HVLED815PF Data brief Description The LED driver 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 Features provide an efficient, compact and cost effective solution for LED driving. It combines a high- 15 W LED driver performance low voltage PWM controller chip and Single stage HPF flyback an 800 V, avalanche rugged Power MOSFET, in the same package. There is no need for the Primary side regulation - no optocoupler optocoupler thanks to the patented primary Power factor > 0.95 sensing regulation (PSR) technique. The device LED driver efficiency > 84% assures protection against LED string fault (open or short).
