COMPLETE LCD SOLUTION FROM TI
Besides the BUFxx703 line of gamma correction
buffers, TI offers a complete set of ICs for the LCD panel
market: source and gate drivers, various power-supply
solutions, as well audio power solutions. Figure 41
shows the Total IC solution from TI.
Audio Power Amplifier for TV Speakers
The TPA3002D2 is a 7W (per channel) stereo audio
amplifier specifically targeted towards LCD monitors
and TVs. It offers highly efficient, filter-free Class-D
operation for driving bridged tied stereo speakers. The
TPA3002D2 is designed to drive stereo speakers as low
as 8
without an output filter. The high efficiency of the
TPA3002D2 eliminates the need for external heatsinks
when playing music. Stereo speaker volume is
controlled with a DC voltage applied to the volume
control terminal offering a range of gain from
–
40dB to
+36dB. Line outputs, for driving external headphone
amplifier inputs, are also DC voltage controlled with a
range of gain from
–
56dB to +20dB. An integrated +5V
regulated supply is provided for powering an external
headphone amplifier. Texas Instruments offers a full line
of linear and switch-mode audio power amplifiers. For
excellent audio performance TI recommends the
OPA364 or OPA353 as headphone drivers. For more
information visit www.ti.com.
Integrated DC/DC Converter for LCD Panels:
TPS65100
The TPS65100 offers 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 device has an integrated
V
COM
buffer. The auxiliary linear regulator controller
can be used to generate the 3.3V logic power rail for
systems powered by a 5V supply rail only. The main
output can power the LCD source drivers as well as the
BUFxx703. 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 BUFxx703 without the
integrated V
COM
buffer could be used for minimum
redundancy and lowest cost. For LCD panels powered
by 5V only, the TPS65100 has a linear regulator
controller that uses an external transistor to provide a
regulated 3.3V output for the digital circuits. Contact the
local sales office for more information.
