General description D D R A FT D R The UBA2072 is a low voltage IC intended to drive Cold Cathode Fluorescent Lamps (CCFLs) for back-lighting applications. The IC contains level-shifters, bootstrap diodes and drivers for the external full-bridge power switches. Furthermore, the UBA2072 has a build-in HF oscillator which determines the operating frequency, a phase shift controller for obtaining constant lamp current, and a PWM generator which is used to set the brightness level of the CCFLs. The UBA2072 is designed to operate over a wide low voltage inverter supply range, up to 30V. The IC can be supplied directly from the inverter supply. A 2. Features Wide supply voltage range (9 V to 30 V DC) Adjustable maximum fault timing Integrated level-shifters Integrated bootstrap diodes Lamp current control Over-voltage control Over-current protection Ignition failure detection Arcing detection Brightness level adjustment through PWM dimming Integrated PWM generator 3. Applications LCD-backlighting, including LCD-TV and LCD-Monitor applications. The IC is intended to drive and control a full-bridge inverter with resonant load circuit for CCFLs, but can also drive an array of External Electrode Fl.
