UBA2070 - CCFL ballast driver IC
The UBA2070 is a high voltage integrated circuit for driving electronically ballasted Cold Cathode Fluorescent Lamps (CCFL) at mains voltages up to 277 V (RMS) (nominal value).
The circuit is made in a 650 V Bipolar CMOS DMOS (BCD) power logic process.
The UBA2070 provides the drive function for the
