Description
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. The device assures protection 
against LED string fault (open or short).
