2.1 Input and Output Connections

The TPS543021EVM is provided with input and output connectors and test points as shown in Table 2-1. Figure 2-1 shows connectors and jumpers placement on the TPS543021EVM board.

A power supply capable of supplying 3A must be connected to J1 through a pair of 20AWG wires. The load must be connected to J2 through a pair of 20-AWG wires. The maximum load current capability is 3A. Wire lengths must be minimized to reduce losses in the wires. Test point TP5 provides a place to monitor the VIN input voltages with TP6 providing a convenient ground reference. TP7 is used to monitor the output voltage with TP8 as the ground reference.
