STMicroelectronics HVLED815PF
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 (>0.90) 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. The device ensures protection against LED string fault (open or short).| Part No. | HVLED815PF |
