USB Type-C™ PD TKT Evaluation Module
This user’s guide describes the TPS65987DDJ evaluation module (USB-C-PD-TKT-EVM). The USB-C-
PD-TKT-EVM allows for the evaluation of the TPS65987DDJ Power Delivery (PD). In addition, the EVM
contains a Type-A to USB Type-C converter, a plug-to-receptacle converter, and a passing through board
for debugging purposes. The USB-C-PD-TKT-EVM uses default configurations to allow for sourcing 45 W
or 60 W by simply using a switch. This document contains an introduction, setup conditions, the EVM
schematics, top- and bottom-board layouts and component views, layout, and a bill of materials (BOM).

1 Introduction
The USB-C-PD-TKT-EVM allows the TPS65987DDJ device to enter default configuration 2 which supports
a 45-W source and default configuration 4 which supports a 60-W source. The USB-C-PD-TKT-EVM
contains a Type-A to USB Type-C converter, a plug-to-receptacle converter, and a passing through board
for debugging purposes.
2 Setup and Switches, Test Points, and LED Descriptions
2.1 LEDs (D1), (D3), (D7), and (D8)
These LEDs highlight if the source board is outputting a 5-V, 9-V, 15-V, or 20-V PD contract respectively.

USB Type-C™ PD TKT Evaluation Module
2.2 LED (D10)
This LED highlights if a valid USB Type-C connection is detected.
2.3 LED (D4)
This LED highlights if a fault condition is detected.
2.4 LED (D5)
This LED highlights if a USB Type-C sink is detected on the CC lines.
2.5 LED (D6)
This LED highlights if the CC2 pin is connected to the cable CC line.
2.6 TP1 (GND), TP3 (GND), TP4 (GND), and TP5 (GND)
These are test points connected to the ground nets for debugging or testing purposes.
2.7 Jumpers (J8) and (J9)
These jumpers connect the VBUS nets from receptacle-to-receptacle and plug-to-receptacle, respectively.
2.8 Switch (S1)
This switch allows the user to select which default configuration to enter.
On – Configuration 4. 60-W Source
OFF - Configuration 2. 45-W Source
2.9 J1 and J6 USB Type-C™ Plugs
These USB Type-C plugs can be connected to any USB Type-C receptacle for a valid connection.
2.10 J3 USB Type-A Plug
This plug is located in the board to allow data transfer from USB Type-C to Type-A.
2.11 J2, J4, J5, J7 USB Type-C™ Receptacles
These are type receptacles that required a USB Type-C plug to establish a valid connection.
2.12 J10 Barrel Jack Connector
This connector requires a minimum 20-VOUT, 3-A IOUT power supply for the board to function as specified.
2.13 TP2 (CC2), TP6 (CC1), TP9 (CC1), and TP10 (CC2)
Use test points TP6 and TP9 to test the data transferred and data communication through CC1 lines on
the receptacle-to-receptacle and plug-to-receptacle board, respectively. Use test points TP2 and TP10 to
test the data transferred and data communication through CC2 lines on the receptacle-to-receptacle and
plug-to-receptacle board respectively.
2.14 TP13 (SCL), TP14 (SDA), and TP15 (GND)
Use this set of tests points for I2C communication in case of user-defined configurations from an SPI
flash. TP13, TP14, and TP15 connect to the I2C1_SCL, I2C1_SDA, and the ground nets, respectively.

3 Using the USB-C-PD-TKT-EVM
To get started with the USB-CPD-TKT-EVM, connect a barrel jack power supply of 20-VOUT, 3-A IOUT
minimum into J10. Next, connect the J1 USB Type-C plug into a USB Type-C receptacle that is PD
compliant. After the connection, depending on the sinking characteristics the LEDs D1, D3, D7, and D8
will highlight the current PD contract.
