UBA2021 - 630V driver IC

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.

Key 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.
