L6585D Combo IC is a PFC and electronic ballast control IC with the following features: 1. Pre-heating and ignition stages can be independently programmed; 2. Ignition voltage can be controlled; 3. Over-current protection PFC in transition mode; 4. Programmable and precise End-of-life protection compliant with all ballast configurations; 5. Auto-adjusting half-bridge over-current control; 6. Automatic re-lamp; 7. 3% oscillator precision; 8. 1.2µs dead time; 9. PFC over-voltage protection and feedback disconnection; 10. Under voltage lock-out.
The L6585D is a combination integrated circuit designed in High-voltage BCD Off-line technology. It embeds a PFC controller, a half-bridge controller, relevant drivers, and the necessary logic to build an electronic ballast. The device features independently programmable pre-heating and ignition phases, ignition voltage control, and transition mode PFC with over-current protection.
