EVLHVLED815W8CV HVLED815 based evaluation board: 8W European range high power factor LED driver with primary constant voltage re

The LED demonstration board is based on a high power factor flyback topology using the STMicroelectronics®HVLED815PF device.

The HVLED815PF is a high-voltage primary switcher intended for operating 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 the optocoupler thanks to the patented primary sensing regulation (PSR) technique.
