1. General description
2. Features
3. Applications
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.
