EVLHVLED815W10F STMicroelectronics

EVLHVLED815W10F 10 W wide-range high power factor isolated 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 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 the optocoupler thanks to the patented primary Features sensing regulation (PSR) technique. The device assures protection against LED string fault (open 10 W LED driver or short). Wide-range input (88 - 265 VAC) Isolated solution Single stage HPF flyback Primary side regulation - no optocoupler Power factor > 0.95 LED driver efficiency > 84% THD < 20% September 2013 DocID025286 Rev 1 1/7 For further information contact your local STMicroelectronics sales office. www.st.comBoard description EVLHVLED815W10F Board description Table 1.
