HCPL-7721, HCPL-0720, CMOS Optocoupler

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 w
