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.

特性 Features

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
