The UBA2074 is a high
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 UBA2074 has a build-in HF oscillator which determines the operating frequency, a phase shift controller for obtaining constant...
