Description

The IC UBA2014 is a monolithic integrated circuit for driving electronically ballasted fluorescent lamps, with mains voltages up to 277 V (RMS) (nominal value).

The circuit UBA2014 is made in a 650 V BCD power-logic process.It provides the drive function for the 2 discrete power
MOSFETs.

Beside the drive function the IC UBA2014 also includes the level-shift circuit, the oscillator function, a lamp voltage monitor, a current control function, a timer function and protections.
