600 V dimmable power IC for compact fluorescent lamps

Rev. 02 — 19 July 2010

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 various protections.

2. Features and benefits

„ Two internal 600 V, 3 Ω max MOST half-bridge power circuits

„ For steady state currents up to 280 mA

„ For ignition currents up to 1.5 A

„ Adjustable preheat time

„ Adjustable preheat current

„ Current controlled operating

„ Single ignition attempt

„ Adaptive non-overlap time control

„ Integrated high voltage level shift function

„ Power-down function

„ Protection against lamp failures or lamp removal

„ Capacitive mode protection

3. Applications

„ 5 W to 25 W dimmable CFLs, provided that the maximum junction temperature is not

exceeded.
