digital and optimized analog control functions
PG-DSO-18-2
PG-DSO-18-1
Features PFC
Description
• Discontinuous Conduction Mode PFC
• Integrated Compensation of PFC Control Loop
• Adjustable PFC Current Limitation
• Adjustable PFC Bus Voltage
The Smart Ballast IC is designed to control a Fluorescent
Lamp Ballast including a Discontinuous Conduction
Mode Power Factor Correction (PFC), a lamp Inverter
Control and a High Voltage Level Shift Half-Bridge
Driver.
Features Lamp Ballast Inverter
The application requires a minimum of external
• Supports Restart after Lamp Removal and End-of- components. There are integrated low pass filters and an
Life Detection even in serial Multi-Lamp Topologies internal compensation for the PFC voltage loop control.
• End-of-Life (EOL) detected by adjustable
Preheating time is adjustable by a single resistor only in
± Thresholds of sensed lamp voltage
the range between 0 and 2000ms. In the same way the
• Rectifier Effect detected by ratio of ± Amplitude of preheating frequency and run frequency are set by
Lamp Voltage
resistors only. The control concept covers requirements
• Detection of different capacitive Mode Operations for T5 lamp ballasts such as detection of end-of-life and
• Adjustable Inverter Overcurrent Shutdown
detection of capacitive mode operation and other
• Self-adaption of Ignition Time from 40ms to 235ms protection measures in serial multilamp topologies.
• Parameters adjustable by Resistors only
• Pb-free lead plating; RoHS compliant
• Halogen-free mould compound, WEEE compliant
ICB1FL03G is easy to use and easy to design and
therefore a basis for a cost effective solution for
fluorescent lamp ballasts.
