Overview

TopologyFlyback Converter
Input voltage230 V
IC revision4

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

  • CFL and TL lamps
