3.1 Physical Access

Table 3-1 lists the TPS2583XAQ1EVM-147 connector functionality, Table 3-2 describes the jumper configuration, Table 3-3 shows LED labels and description and Table 3-4 describes the test point availability.

Table 3-1 Connectors
Connector Component Type Description
J1 Terminal block Power input connector for TPS2583xA-Q1. Connect to a 6-V to 36-V power supply.
J4 USB Type-A connector, plug Upstream facing USB 2.0 Type A connector. Connect to the USB 2.0 host for data pass through to J4 or J8. The power pin of this connector is float.
J3 USB Type-C connector, receptacle Downstream facing USB Type-C connector. Connect to the USB Type-C slave for data pass through from J4 and BC1.2 or USB Type-C identification. USB output power is provided to the slave from the buck converter of the TPS2583xA-Q1 device.
