STMicroelectronics | HVLED805TR

The HVLED805TR is a Off-line LED driver with primary-sensing. This high-voltage primary switcher intended for operating directly from the rectified mains with minimum external parts 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 can also provide a constant output voltage regulation (CV): it makes the application able to work safely when the LED string opens due to a failure.

Features:

• 800 V, avalanche rugged internal power MOSFET
• 5% accuracy on constant LED output current with primary control
• Optocoupler not needed
• Quasi-resonant (QR) zero voltage switching (ZVS) operation
• Internal HV start-up circuit
• Open or short LED string management
• Automatic self supply
• Input voltage feed-forward for mains independent cc regulation

Applications:

• AC-DC led driver applications
• LED retrofit lamps (i.e. E27, GU10)
