High Voltage TFT-LCD Logic Driver
Features
The EL5000A is high voltage TFT-LCD logic driver with
+40V and -30V output swing capability. Manufactured using
the Intersil proprietary monolithic high voltage bipolar
process, it is capable of delivering 100mA output peak
current into 5nF of capacitive load. To simplify external
circuitry, the EL5000A integrates additional logic circuits.
• 3.3V logic supply
FN6167.2
• 40V VON output high level
• -30V VOFF output low level
• 166kHz input logic frequency
• 100mA output peak current
The EL5000A can operate on 3.3V logic supply and high
voltage -30V to +40V output supplies. The EL5000A is
available in a 16 Ld TSSOP. It is specified for operation over
the -20°C to +85°C extended temperature range.

Application Information
General Description
The EL5000A is a high performance 70V TFT-LCD row
driver. It level shifts TTL level timing signals from the video
source into 70VP-P output voltage. Its output is capable of
delivering 100mA peak current into 1nF of capacitive load. It
also incorporates logic to control the output timings. The
logic timing control circuit is powered from 3.3V supply.
Figure 15 shows the system block diagram.
CL capacitors model the capacitive loading appeared at the
inputs of the TFT-LCD panel for the CKV and the CKVB
signals. The CL is typically between 1nF and 5nF.
In addition to switches SW1, SW2, SW3, and SW4, a fifth
switch is added to reduce the power dissipation and shape
the output waveform. Figure 17 shows the location of the
additional SW5 switch.
Input Signals
The device performs beside of level transformation also logic
operation between the input signals:
• STV - Vertical Sync Timing signal, frequency range around
60Hz
• CPV - Horizontal Sync Timing signal, frequency range up
to 166kHz

FIGURE 17. BI-DIRECTIONAL SWITCHES
Output Signals
The output signals, CKV and CKVB are generated by
EL5000A internal switches. Figure 16 depicts the simplified
schematic of the output stage and interface.
In reality, each switch consists of two such switches, one for
the positive discharge and one for the negative discharge,
see Figure 18.

Due to the actual solid-state construction of the switches, the
capacitors CL does not get discharged entirely. The amount
of left over charges depends on the value of the voltages of
VON and VOFF on the capacitors.

Internal Logic Block Diagram
Figures 19 and 20 show the internal block diagram. In order
to reduce power dissipation, most of the logic circuitry is
powered from 3.3V logic supply. The output of the 3.3V logic
is level-shifted to drive the output switches.

Output Waveforms
Figure 22 shows the delay time between the incoming
horizontal sync timing pulse CPV and the generated output
pulses. Δt is dependent mainly on the value of CL. Figure 23
shows the effect of STV.
Figure 21 shows a typical CKV and CKVB output
waveforms. The output droop rate depends on the external
discharge resistor value and the output capacitor load.

Power Dissipation
+40V
The dissipated power in R3 and R6 could be calculated as
follows:
23V
We assume that:
+17 V
• VON = 40V
+3.3 V
0V
• VOFF = -20V
23V
• H sync timing frequency = 60kHz
• CL = 5nF
-20V
The value of VL (the left over voltage) in the capacitors in
that case is 23V for the positive discharge and 3.3V for the
negative discharge.
FIGURE 25.
The voltage change across the capacitor is therefore 23V;
see Figure 25.
The stored energy in the capacitor is shown in Equation 1:
2
2
-9
1/2 × V C = 1/2 × 23 × 5 × 10 = 132μJ
(EQ. 1)
The energy, which is stored in the capacitor, will be
dissipated on the resistor; see Figure 26. The switch will
close 2 x 60,000 in every second.
The process will be repeated 2 times for the CKV and the
CKVB. In 120,000 cycles per second, the power dissipation
in R3 and R6 becomes Equation 2:
2 × 1.32 × 10
-6
3
× 60 × 10 = 160mW
11
(EQ. 2)
FIGURE 26.
For different values of VON, VOFF, CL and H sync timing
frequency, the worst case dissipation can be calculated in a
similar matter. The value of the R3 and R6 must be selected
such that the capacitor CL is discharged via R3 or R6 resistor
in one half period of the H sync timing.
Figures 13 and 14 show the total power dissipation over a
range of possible voltages, operating frequencies and loads.
Care should be taken to prevent the power from exceeding
the maximum rating of the package, as shown in Figure 13.
