GENERAL DESCRIPTION
The UBA2021 is a high-voltage IC intended to drive and control Compact Fluorescent Lamps (CFL) or fluorescent TL-lamps. It contains a driver circuit for an external half-bridge, an oscillator and a control circuit for starting up, preheating, ignition, lamp burning and protection.

FEATURES
• Adjustable preheat and ignition time
• Adjustable preheat current
• Adjustable lamp power
• Lamp temperature stress protection at higher mains voltages
• Capacitive mode protection
• Protection against a too-low drive voltage for the power MOSFETs.
