Bidirectional pin acting both as fault signaling output and input, allowing external fault
interfacing to operate via the integrated fault timer.
Brightness level adjustment through PWM dimming.
Integrated PWM generator.
Power-down mode.
Communication pin for master / slave operation.
DC blocking capacitor pre-charging sequence.
Supply clamp (UBA2071 only).
LCD-backlighting, including LCD-TV and LCD-monitor applications. The IC is intended
to drive and control a half bridge inverter with resonant load circuit for CCFLs, but can
also drive an array of External Electrode Fluorescent Lamps (EEFLs).
