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.

2. Features

I Adjustable preheat and ignition time.

I Adjustable preheat current.

I Adjustable lamp power.

I Lamp power independent from mains voltage variations.

I Overpower protection.

I Lamp temperature stress protection at higher mains voltages.

I Capacitive mode protection.

I Protection against a drive voltage that is too low for the power MOSFETs.
