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
sensing regulation (PSR) technique. The device
assures protection against LED string fault (open
or short).
