GENERAL DESCRIPTION
UBA2014
The IC is a monolithic integrated circuit for driving
electronically ballasted fluorescent lamps, with mains
voltages up to 277 V (RMS) (nominal value).
The circuit 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 also includes the level-shift
circuit, the oscillator function, a lamp voltage monitor, a
current control function, a timer function and protections.
