Half bridge control IC for CCFL backlighting
12. Application information
Figure 19 shows an example backlighting con?guration, where the inverter is supplied
from a high voltage DC source and the IC is supplied by means of a ? V/ ? t supply (C14,
C15, Z1 and D1). Two lamps are connected, each to the output of its own transformer. The
leakage inductance of this transformer provides the ballast impedance for the lamps. An
analog voltage is converted to a PWM signal to provide for the desired brightness level.
Lamp short detection is done via the lamp voltage sensing, D13 and D23, and the
NONFAULT pin.
Figure 20 shows an example of a balanced application using one UBA2071 and one
UBA2073.
