1 / 16 page 1. 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. 2. Features I Adjustable preheat and ignition time. I Adjustable preheat current. I Adjustable lamp power. I Lamp power independent from mains voltage variations. I Overpower protection. I Lamp temperature stress protection at higher mains voltages. I Capacitive mode protection. I Protection against a drive voltage that is too low for the power MOSFETs. 3.
