UBA2021
Datasheet
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 power independent from mains voltage variations.
- Overpower protection.
- Lamp temperature stress protection at higher mains voltages.
- Capacitive mode protection.
- Protection against a drive voltage that is too low for the power MOSFETs.
