Off-line LED driver with primary-sensing and high power factor up to 7W

The HVLED807PF 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 • High power factor capability (> 0.9)\n• 800 V, avalanche rugged internal 11 Ω power MOSFET\n• Internal high-voltage startup\n• Primary sensing regulation (PSR)\n• +/- 5% accuracy on constant LED output current• Quasi-resonant (QR) operation\n• Optocoupler not needed\n• Open or short LED string;
