Product data sheet

1. General description

The UBA2025 is a high voltage power IC intended to drive and control a Compact

Fluorescent Lamp (CFL). It contains a half bridge power circuit, an oscillator, and a control

circuit for starting up, preheating, ignition, lamp burning, and protection.

2. Features

I Two internal 600 V, 3 Ω max NMOST half bridge powers

I For steady state half bridge currents up to 280 mA

I For ignition half bridge currents up to 1.5 A

I Adjustable preheat and ignition time

I Adjustable preheat current

I Adjustable lamp power

I Lamp temperature stress protection at higher mains voltages

I Capacitive mode protection

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

3. Applications

I 5 W to 25 W CFLs provided that the maximum junction temperature is not exceeded.
