UBA2021
630 V driver IC for CFL and TL lamps
Rev. 04 — 25 July 2008
Product data sheet
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.
