COMPLETE LCD SOLUTION FROM TI
In addition to the BUFxx704 line of gamma correction
buffers, TI offers a complete set of ICs for the LCD panel
market, including source and gate drivers, timing
controllers, various power-supply solutions, and audio
power solutions. Figure 27 shows the total IC solution
from TI.
AUDIO POWER AMPLIFIER FOR TV
SPEAKERS
The TPA3005D2 is a 6 W (per channel) stereo audio
amplifier specifically targeted towards LCD monitors
and TVs. It offers highly efficient, filter-free Class-D
operation for driving bridge-tied stereo speakers. The
TPA3005D2 is designed to drive stereo speakers as low
as 8
without an output filter. The high efficiency of the
TPA3005D2 eliminates the need for external heatsinks
when playing music. The TPA3008D2 is similar to the
TPA3005D2, but is capable of 8 W of output power.
Texas Instruments offers a full line of linear and
switch-mode audio power amplifiers. For more
information, visit www.ti.com. For excellent audio
performance, TI recommends the OPA364 (SBOS259)
or OPA353 (SBOS103) as headphone drivers.
INTEGRATED DC/DC CONVERTERS FOR
LCD PANELS: TPS65100 and TPS65140
The TPS65100 and TPS65140 offer a very compact
and small power supply solution to provide all three
power-supply voltages required by TFT (thin film
transistor) LCD displays. Additionally the devices have
an integrated V
COM
buffer. The auxiliary linear regulator
controller can be used to generate the 3.3 V logic power
rail for systems powered by a 5 V supply rail only. The
main output can power the LCD source drivers as well
as the BUFxx704. An integrated adjustable charge
pump doubler/tripler provides the positive LCD gate
drive voltage. An externally adjustable negative charge
pump provides the negative gate drive voltage. The
TPS65100 has an integrated V
COM
buffer to power the
LCD backplane. A version of the BUFxx704 without the
integrated V
COM
buffer could be used for minimum
redundancy and lowest cost. For LCD panels powered
by 5 V only, the TPS65100 has a linear regulator
controller that uses an external transistor to provide a
regulated 3.3 V output for the digital circuits. Contact
the local sales office for more information.
