FEATURES
DESCRIPTION
•
•
•
The BUFxx703 are a series of multi-channel buffers
targeted towards gamma correction in high-resolution
liquid crystal display (LCD) panels. The number of
gamma correction channels required depends on a
variety of factors and differs greatly from design to
design. Therefore, various channel options are
offered. For additional space and cost savings, a
VCOM channel with higher current drive capability is
integrated in the BUF07703 and BUF05703.

A flow-through pinout has been adopted to allow
simple printed circuit board (PCB) routing and
maintain the cost-effectiveness of this solution. All
inputs and outputs of the BUFxx703 incorporate
internal ESD protection circuits that prevent functional
failures at voltages up to 4kV HBM and 1.5kV CDM.
The various buffers within the BUFxx703 are carefully
matched to the voltage I/O requirements for the
gamma correction application. Each buffer is capable
of driving heavy capacitive loads and offers fast load
current switching. The VCOM channel has increased
output drive of > 100mA and can handle even larger
capacitive loads.
The BUF07703 is available in the HTSSOP
PowerPAD™ package for dramatically increased
power dissipation capability. The BUF06703 and
BUF05703 are available in standard TSSOP-16 and
TSSOP-14 packages.

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.

APPLICATION INFORMATION
The requirements on the number of gamma
correction channels vary greatly from panel to panel.
Therefore, the BUFxx703 series of gamma correction
buffers offers different channel combinations. The
VCOM channel can be used to drive the VCOM node on
the LCD panel.
The BUFxx703 buffers the various nodes on the
gamma correction resistor ladder. The low output
impedance of the BUFxx703 forces the external
gamma correction voltage on the respective
reference node of the LCD source driver. Figure 35
shows an example of the BUFxx703 in a typical block
diagram driving an LCD source driver with 6-channel
gamma correction reference inputs.
Gamma correction voltages are often generated
using a simple resistor ladder, as shown in Figure 35.

INPUT VOLTAGE RANGE GAMMA BUFFERS
Figure 36 shows a typical gamma correction curve
with 10 gamma correction reference points (GMA1
through GMA10). As can be seen from this curve, the
voltage requirements for each buffer varies greatly.
The swing capability of the input stages of the various
buffers in the BUFxx703 is carefully matched to the
application. Using the example of the BUF07703 with
six gamma correction channels, buffers 1 to 3 have
input stages that include VDD, but will only swing
within 1V to GND. Buffers 1 through 5 have only a
single NMOS input stage. Buffers 4 through 6 have
only a single PMOS input stage. The input range of
the PMOS input stage includes GND.
Connect buffer 1 to the gamma voltage closest to
VDD, and buffers 2 and 3 to the sequential voltages.
Buffer 6 should be connected to the gamma
correction voltage closest to GND (or the negative
rail), buffers 4 and 5 to the sequential higher
voltages.
COMMON BUFFER (VCOM)
The common buffer output of the BUF07703 and
BUF05703 has a greater output drive capability than
the gamma correction buffers, to meet the heavier
current demands of driving the common node of the
LCD panel. It was also designed to drive heavier
capacitive loads and still remain stable, as shown in
Figure 37.

OUTPUT VOLTAGE SWING GAMMA
BUFFERS
The output stages have been designed to match the
characteristic of the input stage. Once again using
the example of the BUF07703 means that the output
stage of buffer 1 swings very close to VDD, typically
VCC − 100mV at 5mA; its ability to swing to GND is
limited. Buffers 2 and 3 have smaller output stages
with slightly larger output resistances, as they will not
have to swing as close to the positive rail as buffer 1.
Buffers 4 through 6 swing closer to GND than VDD.
Buffer 6 is designed to swing very close to GND,
typically GND + 100mV at a 5mA load current. See
the Typical Characteristics for more details. This
approach significantly reduces the silicon area and
cost of the whole solution. However, due to this
architecture, the correct buffer needs to be connected
to the correct gamma correction voltage.
Figure 37. Phase Shift vs Load Capacitance
CAPACITIVE LOAD DRIVE
The BUFxx703 has been designed to be able to
sink/source DC currents in excess of 10mA. Its output
stage has been designed to deliver output current
transients with little disturbance of the output voltage.
However, there are times when very fast current
pulses are required. Therefore, in LCD source-driver
buffer applications, it is quite normal for capacitors to
be placed at the outputs of the reference buffers.
These are to improve the transient load regulation.
These will typically vary from 100pF and more. The
BUFxx703 gamma buffers were designed to drive
capacitances in excess of 100pF and retain effective
phase margins above 50°, as shown in Figure 38.

When a greater number of gamma correction
channels are required, two or more BUFxx703
devices can be used in parallel, as shown in
Figure 39. This provides a cost-effective way of
creating more reference voltages over the use of
quad-channel op amps or buffers. The suggested
configuration in Figure 39 simplifies layout. The
various different channel versions provide a high
degree of flexibility and also minimize total cost and
space. Table 1 lists a variety of gamma combinations
for applications with more than 10 channels.

MULTIPLE VCOM CHANNELS
In some LCD panels, more than one VCOM driver is
required for best panel performance. Figure 40 uses
three BUF07703s to create a total of 18
gamma-correction and three VCOM channels. This
solution saves considerable space and cost over the
more conventional approach of using five or six
quad-channel buffers or op amps.

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 8Ω 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 VCOM 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 VCOM buffer to power the LCD backplane.
A version of the BUFxx703 without the integrated
VCOM 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.

GENERAL PowerPAD DESIGN
CONSIDERATIONS
The BUF07703 is available in the thermally enhanced
PowerPAD family of packages. These packages are
constructed using a downset leadframe upon which
the die is mounted; see Figure 42(a) and (b). This
arrangement results in the lead frame being exposed
as a thermal pad on the underside of the package;
see Figure 42(c). Due to this thermal pad having
direct thermal contact with the die, excellent thermal
performance is achieved by providing a good thermal
path away from the thermal pad.
The PowerPAD package allows for both assembly
and thermal management in one manufacturing
operation. During the surface-mount solder operation
(when the leads are being soldered), the thermal pad
can also be soldered to a copper area underneath the
package. Through the use of thermal paths within this
copper area, heat can be conducted away from the
package into either a ground plane or other
heat-dissipating device. Although there are many
ways to properly heatsink the PowerPAD package,
the following steps illustrate the recommended
approach.
1. Prepare the PCB with a top-side etch pattern,
(see Pin Configurations). There must be etching
for the leads as well as etch for the thermal pad.
2. Place 18 holes in the area of the thermal pad.
These holes must be 13 mils in diameter. Keep
them small, so that solder wicking through the
holes is not a problem during reflow.
3. Additional vias may be placed anywhere along
the thermal plane outside of the thermal pad
area. This helps dissipate the heat generated by
the BUF07703 IC. These additional vias may be
larger than the 13-mil diameter vias directly under
the thermal pad. They can be larger because
they are not in the thermal pad area to be
soldered, so that wicking is not a problem.
4. Connect all holes to the internal ground plane.
5. When connecting these holes to the ground
plane, do not use the typical web or spoke via
connection methodology. Web connections have
a high thermal resistance connection that is
useful for slowing the heat transfer during
soldering operations. This makes the soldering of
vias that have plane connections easier. In this
application, however, low thermal resistance is
desired for the most efficient heat transfer.
Therefore, the holes under the BUF07703
PowerPAD package must make their connection
to the internal ground plane with a complete
connection around the entire circumference of the
plated-through hole.
6. The top-side solder mask must leave the
terminals of the package and the thermal pad
area with its five holes (dual) or nine holes (quad)
exposed. The bottom-side solder mask must
cover the five or nine holes of the thermal pad
area. This prevents solder from being pulled
away from the thermal pad area during the reflow
process.
7. Apply solder paste to the exposed thermal pad
area and all of the IC terminals.
8. With these preparatory steps in place, the
BUF07703 IC is simply placed in position and run
through the solder reflow operation as any
standard surface-mount component. This results
in a part that is properly installed.
For a given qJA, the maximum power dissipation is
calculated by the following formula:
PD =
(
TMAX - TA
qJA
(
Where:
•
•
•
•
•
•
PD = maximum power dissipation (W)
TMAX = absolute maximum junction temperature
(+150°C)
TA = free-ambient air temperature (°C)
qJA = qJC + qCA
qJC = thermal coefficient from junction to case
(°C/W)
qCA = thermal coefficient from case-to-ambient air
(°C/W)
This lower thermal resistance enables the BUF07703
to deliver maximum output currents even at high
ambient temperatures.
