CFL power IC
Rev. 01 — 16 October 2009
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 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.
