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 UBA207.
• 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. ORDERING INFORMATION
