HVLED805

Off-line LED driver with primary-sensing

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)
