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).
