ICB1FL02G
Smart Ballast Control IC for
Fluorescent Lamp Ballasts
Product Highlights
• Lowest Count of external Components
• HV-Driver with coreless Transformer Technology
• Improved Reliability and minimized Spread due to
digital and optimized analog control functions
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
