UBA2014 600 V driver IC for HF uorescent lamps Rev. 04 16 October 2008 Product data sheet 1. General description The IC is a monolithic integrated circuit for driving electronically ballasted uorescent lamps, with mains voltages up to 277 V (RMS) (nominal value). The circuit is made in a 650 V Bipolar CMOS DMOS (BCD) power-logic process. It provides the drive function for the two discrete power MOSFETs. Besides the drive function, the IC also includes the level-shift circuit, the oscillator function, a lamp voltage monitor, a current control function, a timer function and protections. 2.
