8 / 60 page  ICB2FL03G Controller for Fluorescent Lamp Ballasts Final Data Sheet 8 V1.1, 2013-08-14 2nd Generation FL-Controller for Fluorescent Lamp Ballasts Product Highlights • Lowest count of external components • 650 V half-bridge driver with coreless transformer technology • Supports Customer In-Circuit Test Mode for reduced tester time • Supports multi-lamp designs (series connection) • Integrated digital timers up to 40 seconds • Numerous monitoring and protection features for highest reliability • Very high accuracy of frequencies and timers over the whole temperature range • Very low standby losses PFC Features • Discontinuous mode PFC for load range 0 to 100% • Integrated digital compensation of PFC control loop • Improved compensation for low THD of AC input current, also in DCM operation • Adjustable PFC current limitation Lamp Ballast Inverter Features • Adjustable detection of overload and rectifier effect (EOL) • Detection of capacitive load operation • Improved ignition control allows operation close to the magnetic saturation of the lamp inductors • Restart with skipped preheating on short interruptions of line voltage (for emergency lighting) • Parameters adjustable by resistors only • Pb-free lead plating; RoHS-compliant Figure 1 Typical Application Circuit of Ballast for a Single Fluorescent Lamp Description The FL controller ICB2FL03G is designed to control fluorescent lamp ballast, including a discontinuous mode Power Factor Correction (PFC), lamp inverter control and a high-voltage level shift half-bridge driver. The control concept covers requirements for T5 lamp ballasts for single and multi-lamp designs (series connection supported). ICB2FL03G is based on the 2nd-generation FL controller technology, is easy to use and simple to design in. This makes the ICB2FL03G a basis for cost-effective solutions for fluorescent lamp ballasts with high reliability. Figure 1 shows a typical application circuit of ballast for a single fluorescent T8 lamp with current mode preheating. PFCZCD PFCGD PFCVS PFCCS HSGD HSVCC HSGND LSGD LSCS VIN |
