1 Introduction

The TPS65680 EVM uses the TPS65680 device to deliver 18 high-voltage level-shifter output channels to support the high-voltage gate signals of gate-in-array (GOA) or gate-in-panel (GIP) LCD displays. The EVM makes it easy to examine the programmability and performance of the TPS65680 device.

1.1 Requirements

The IC on the EVM is not programmed and the outputs will only toggle after a pattern is loaded. The EVM comes with the USB2ANY interface adapter and the connectors. For programming the device, you additionally must have a host computer, and a DC power supply. To operate the level shifters, 2 square wave outputs of a frequency generator or microcontroller are necessary.

1.1.1 Power Supplies

In order to operate this EVM, 3 DC power supplies, PS1, PS2, and PS3, with the following requirements are needed:

• PS1 to supply VIN: 2.7 V to 5.5 V capable of 0.5 A

• PS2 to supply VGL: –18 V to –4 V capable of 1 A

• PS3 to supply VGH: 9 V to 40 V capable of 1 A

1.1.2 Digital Inputs

The output signals of a gate signal level shifter on an LCD TFT need to be synchronized to the timing controller that delivers the image content. To keep TPS65680 synchronised to the timing controller signals, just 2 digital input signals are necessary:

• LN_CLK is the input signal for the TPS65680 internal PLL. This fixed frequency signal is often set to

the line frequency.

• A rising edge on LS_START starts the programmed pattern from the programmed start address. This

fixed frequency signal is normally set to the frame frequency, for example; 60 Hz, 120 Hz, 240 Hz, and so forth.

Introduction

1.1.3 Host Computer

A computer with a USB port is required program the TPS65680 on the EVM. The TPS65680 software runs on a personal computer (PC) and communicates with the EVM through a USB port.

The minimum requirements for the PC are:

• Microsoft Windows 7 or 10 operating system

• 1 USB port

• A minimum of 280MB of free hard disk space (610MB recommended)

• A minimum of 512MB of RAM

1.1.4 Software

Texas Instruments provides the software necessary to program the TPS65680 and evaluate the IC functionality. After you are approved, download the software and install it on your computer.

In addition to ease the first start with the device, TI provides some standard patterns and a How-To-Start Video. All of these are included in your 'mySecure Software' folder which included this user's guide.

1.2 Applications

• LCD and OLED panels using GIP and GOA technology

• TV, monitor, notebook, and tablet PC

4.2 Input Connectors

4.2.1 J4 – LN_CLK - Input and GND Connector

This header is the connection for the LN_CLK input square wave signal. Connect a frequency generator or microcontroller output between pins 1 and 2 (LN_CLK) and pins 3 and 4 (GND) to supply the device with the input signal for the internal PLL. The square wave needs to have a frequency from 40 kHz to 500 kHz and a duty cycle of 40% to 60%.

4.2.2 J5 – LS_START - Input and GND Connector

This header is the connection for the LS_START input signal. Connect a frequency generator or microcontroller output between pins 1 and 2 (LS_START) and pins 3 and 4 (GND) to supply the device with the input signal starting the programmed output pattern from the programmed start address. The LS_START pulse needs to have a pulse width of 15 µs to 500 µs.

4.2.3 J6, J52, and S2 – LS_CNTRL - Input and GND Connectors

The header J6 is the connection for the LS_CNTRL input signal. For programming the TPS65680 this signal needs to be low, if this signal is set high, the IC is in active mode and the device can be controlled via the LN_CLK and LS_START signals.

This signal can be driven from an external source, via header J52 or from the GUI.

• GUI: Set switch S2 to SW side

• J52: Set switch S2 to J52 side and use the jumper on J52 to drive the signal high (connect middle pin

to pin 1 (VIN)) or low (connect middle pin to pin 3 (GND))

• External source: Remove the jumper from header J52 and set switch S2 to J52.

Connector and Test Point Descriptions

4.3 Level-Shifter Output Connectors

4.3.1 J36, J38, J12, J14, J16, J18, J20, J22, J24, J6, J28, J30, J32, J34, J40, J46, J42, and J44 – GSP1, GSP2, GCK1 to GCK12, GCP, VSS, GGP1 and GGP2 - Output and GND Connectors

These headers are the connection of the 18 level-shifter outputs. Connect a scope probe between pins 1 and 2 (GND) and pins 3 and 4 (output) to measure this specific level shifter output.

4.3.2 J35, J37, J11, J13, J15, J17, J19, J21, J23, J25, J29, J31, J33, J39, J45, J41, and J43 – Connectors to add load to the level shifter outputs

These headers can be used to add capacitive or RC load to the respective one of the 18 level shifter outputs. Connect a jumper between pins 1 and 2 (C) to add a capacitive load to the respective level shifter output or connect a jumper between pins 2 and 3 (RC) to add an RC load to the respective level shifter output.

4.3.3 J54, J55, J56, J57, J59, J60, J61, J62, J63, J64, and J65 – Connectors to add identical loads to 2 level shifter outputs to measure charge sharing

These headers can be used to add identical RC loads to the respective 2 of the 12 level shifter clock outputs that are used during charge sharing. Connect a jumper on one of the headers J54 to J59 to add a load to one of the channels GCK1 to GCK6 and another jumper on one of the headers J60 to J65 to add an RC load to one of the channels GCK7 to GCK12. If the 2 resistors R26 and R27 and the 2 capacitors C49 and C50 have the identical values, the output voltages of the channels that are sharing their charge should meet at the voltage V

NOTE: Be aware that capacitors with the identical theoretical value do not match in reality. For

identical capacitance values you need to measure the capacitors and select two that have identical values before applying them to the EVM.

Connector and Test Point Descriptions

4.4 Additional Jumpers and Connectors

4.4.1 J49 and J43 – CS1 and CS2 - Enable Gate Voltage Shaping (GVS) or Charge Sharing (CS)

These headers are used to decide if CS or GVS is used when a channel is connected to the CSx pins. CS1 and CS2 need to be connected to the same value, either both to GVS (CS1 and CS2 pins are then connected through the resistors R1 and R3 to GND) or both to CS (CS1 and CS2 pins are connected together through the resistor R2).

If GVS is selected, a clock output can be discharged to GND through resistor R1 or R3 before it changes its state from high to low or vice versa.

If CS is selected, 2 clock outputs can share their charge before changing their opposite states (one needs to be high, the other one needs to be low at the beginning of the CS phase).

4.4.2 J10 – I2C_SEL- Select Between I2C Address 0x42 or 0x43

The I2C_SEL input defines the last bit of the I2C address of TPS65680. This makes it possible to easily use 2 TPS65680 on one I2C bus in high-resolution panels. Connect this pin to GND by shorting pins 2 and 3 to set the I2C address to 0x42. Connect this pin to 3V3 by connecting pins 1 and 2 to set the I2C address to 0x43.

4.4.3 J53 – USB2ANY

With the 10-pin header J53 the EVM connects through the USB2ANY interface box to a PC. The installed GUI communicates through the I2C pins 9 and 10 of J53 with the TPS65680 on the EVM. Pin 1 of J53 can drive LS_CNTRL via S2, pin 2 of J53 connects I2C_SEL to the GUI. The GUI reads this voltage before any communication with the IC.

www.ti.com

4.4.4 J7 – 3.3V - Voltage Limitation for USB2ANY

The GUI is able to read the voltage on the I2C_SEL pin through pin 2 of J53. As USB2ANY allows a maximum voltage of 3.6 V on the pins of J53, it is necessary to limit the voltage on I2C_SEL. The 3.3-V LDO U2 creates a logic voltage out of VIN that does not exceed 3.3 V.

4.4.5 J50 – Connect C8 to the OTP_LDO pin

This header connects a capacitor (C8) to the OTP_LDO pin. A jumper on this header is necessary if the content of the registers is stored in the OTP non-volatile memory. The voltage on this pin is observed on the header J9. While the OTP is written, the voltage on this pin is created via an internal LDO from VGH. To keep the voltage during the write process stable, the capacitor needs to be connected via a jumper on header J50.

5 Test Setup

5.1 EVM Operation

Three different voltage supplies are necessary to operate the EVM. These can be delivered by three power supplies or by an LCD bias device, like TPS65175, TPS65640, or alike. The digital input signals LN_CLK and LS_START are delivered by the timing controller in the final application, but for evaluation purposes, frequency generator or microcontroller outputs can be used as well.

The TPS65680 on the EVM is not pre-programmed, so it needs to be programmed before the outputs can deliver a pattern. TI delivers some pre-defined patterns for the first tests. Download these patterns from your 'mySecure Software' page in your myTI account on the web.

To ease the first setup of the EVM, review the video in your 'mySecure Software' page in your myTI account on the web.

5.2 Software Setup to Change the Output Voltages and Configuration

Download the software (see Section 1.1.4) and the installation instructions (zipped file), unpack it, and execute the setup.exe file. This installs the up-to-date software version. TI recommends removing older versions before installing the updated one.

5.3 Hardware Setup

Connect the three power supplies to the following headers:

• J1: Connect the power supply for VIN (2.7 V to 5.5 V) to this header. The absolute maximum voltage for VIN is 6 V.

• J2: Connect the power supply for VGH (9 V to 40 V) to this header. The absolute maximum voltage for VGH is 42 V.

• J3: Connect the power supply for VGL (–18 V to –4 V) to this header. The absolute maximum voltage for VGL is –20 V.

CAUTION

Make sure that the voltage delta from VGH to VGL never exceeds 55 V!

Connect the outputs of the frequency generator or microcontroller to J4 (LN_CLLK) and J5 (LS_START). Connect the 10-pin ribbon cable out of the HPA-665 bag to J53, the other end to the USB2ANY box and

with the USB-cable the other side of the USB2ANY box to the PC. For the first startup, set the switch S2 to SW (for software), and the two jumpers on J43 and J49 to GVS.

Test Setup

5.4 Software Operation

After the installation of the software, an icon with the name TPS65680 appears on the desktop (if checked within the installation) of the host computer. If it does not, browse the program files in the Start menu for the software. The default location is All Programs → Texas Instruments → TPS65680 EVM.

After connecting the USB interface adapter to the host computer, the software can be started. At the first start-up, the system asks to update the firmware of the adapter (follow the firmware update instructions given). After confirmation of this update, the software window shown in Figure 3 appears.

Please go to Help → User Manual for a detailed description of all GUI functions.
