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).
