UBA2071; UBA2071A
Half bridge control IC for CCFL backlighting
I Bidirectional pin acting both as fault signaling output and input, allowing external fault
interfacing to operate via the integrated fault timer.
I Brightness level adjustment through PWM dimming.
I Integrated PWM generator.
I Power-down mode.
I Communication pin for master / slave operation.
I DC blocking capacitor pre-charging sequence.
I Supply clamp (UBA2071 only).
3. Applications
I 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).
4. Quick reference data
Table 1. Quick reference data.
T amb = 25 ° C; V VDD = 12 V; R IREF = 33 k ? ; V EN = V VDD and CPWM connected to a capacitor, unless
otherwise speci?ed. All voltages are measured with respect to signal ground (SGND, pin 10). SGND
and PGND connected together. Currents are positive when ?owing into the IC.
