Beschreibung

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 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.
