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.
- 8 W LED driver - constant voltage
- EU range input (200 - 265 Vac)
- Isolated solution
- Single stage HPF flyback
- Primary side regulation - no optocoupler
- Power factor > 0.90
- LED driver efficiency > 87%
- Harmonics distortion meets EC 61000-3-2 Class D
