600 V driver IC for HF fluorescent lamps

Rev. 04 — 16 October 2008

Product data sheet

1. General description

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.

2. Features

I Adjustable preheat time

I Adjustable preheat current

I Current controlled operating

I Single ignition attempt

I Adaptive non-overlap time control

I Integrated high-voltage level-shift function

I Power-down function

I Protection against lamp failures or lamp removal

I Capacitive mode protection

3. Applications

I The circuit topology enables a broad range of ballast applications at different mains

voltages for driving lamp types from T8, T5, PLC, T10, T12, PLL and PLT, for example.
