Product specification
600 V CCFL ballast driver IC
UBA2070
FEATURES
• Current controlled operation
• Adaptive non-overlap time control
• Integrated high voltage level shift function
• Power-down function
• Protected against lamp failures or lamp removal
• Capacitive mode protection.
APPLICATION
• The circuit topology enables a broad range of backlight
inverters.
GENERAL DESCRIPTION
The UBA2070 is a high voltage integrated circuit for driving
electronically ballasted Cold Cathode Fluorescent Lamps
(CCFL) at mains voltages up to 277 V (RMS) (nominal
value). The circuit is made in a 650 V Bipolar CMOS
DMOS (BCD) power logic process. The UBA2070
provides the drive function for the two discrete MOSFETs.
Besides the drive function the UBA2070 also includes the
level-shift circuit, the oscillator function, a lamp voltage
monitor, a current control function, a timer function and
protections.
