www.DataSheet4U.com INTEGRATED CIRCUITS DATA SHEET UBA2070 600 V CCFL ballast driver IC Product specification Supersedes data of 2001 Sep 27 2002 Oct 24 Philips Semiconductors 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. ORDERING INFORMATION 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.
