The UBA2211 family of integrated circuits are a range of high voltage monolithic ICs for driving Compact Fluorescent Lamps (CFL) in half-bridge configurations. The family is specifically designed to provide easy integration of lamp loads across a range of burner power and mains voltages.

• Integrated half bridge switches suitable for 220 V mains applications
• UBA2211A: Half bridge switches of 13.5 Ohm for ignition current up to 0.9 A and up to 11 W lamp power
• UBA2211B: Half bridge switches of 9 Ohm for ignition current up to 1.35 A and up to 18 W lamp power
• UBA2211C: Half bridge switches of 6.6 Ohm for ignition current up to 1.85 A and up to 23 W lamp power
• Current controlled preheat with adjustable preheat time and preheat current
• Lamp power independent from mains voltage variations
• Lamp inductor saturation protection during ignition
• Overtemperature protection
• System shutdown at burner end of life
• Same controller functionality ensuring power scaling on a complete range of CFLs
• Pin-compatible with UBA2213 family

• Compact Fluorescent Lamps up to 23 W for indoor and outdoor applications
