Overview
| Topology | Half-Bridge Converter symmetrical isolated |
| Input voltage | 230 V |
| IC revision | 4 |
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.
Typical applications
- Fluorescent TL lamps
- Fluorescent TL lamps
