UBA2028
600 V dimmable power IC for compact fluorescent lamps
Rev. 01 — 9 October 2009
Product data sheet
1. General description
The UBA2028 is a high voltage power IC that drives and controls electronically ballasted
Compact Fluorescent Lamps (CFLs). The IC includes a Metal-Oxide-Semiconductor
Transistor (MOST) half bridge power circuit, a dimming function, a high voltage level shift
circuit, an oscillator function, a lamp voltage monitor, a current control function, a timer
function and protections.
2. Features
I Two internal 600 V, 3 Ω max MOST half bridge powers.
I For steady state currents up to 280 mA.
I For ignition currents up to 1.5 A.
I Adjustable preheat time.
I Adjustable preheat current.
I Current controlled operating.
I Single ignition attempt.
I Adaptive non-overlap time control.
I Integrated high voltage level shift function.
I Power-down function.
I Protection against lamp failures or lamp removal.
I Capacitive mode protection.
3. Applications
I 5 W to 25 W dimmable CFLs, provided that the maximum junction temperature is not
exceeded.
