UBA2014T: 600 V driver IC for HF fluorescent lamps

Overview

The IC is a monolithic integrated circuit for driving electronically ballasted fluorescent lamps, with mains voltages up to 277 V (RMS) (nominal value). 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.

Features
