600 V driver IC for HF ﬂuorescent lamps

UBA2014

FEATURES

• Adjustable preheat time

• Adjustable preheat current

• Current controlled operating

• Single ignition attempt

• Adaptive non-overlap time control

• Integrated high-voltage level-shift function

• Power-down function

• Protection against lamp failures or lamp removal

• Capacitive mode protection.

APPLICATIONS

The circuit topology enables a broad range of ballast

applications at different mains voltages for driving lamp

types from e.g. T8, T5, PLC, T10, T12, PLL and PLT.

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 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.
