4.1 Input and Output Connections

The TPS568231EVM is provided with input and output connectors and test points as shown in Table 4-1. A power supply capable of supplying 6 A must be connected to J1 through a pair of 20-AWG wires. The load must be connected to J2 through a pair of 20-AWG wires. The maximum load current capability is 8 A. Wire lengths must be minimized to reduce losses in the wires. Test point TP2 provides a place to monitor the VIN input voltages with TP4 providing a convenient ground reference. TP7 is used to monitor the output voltage with TP10 as the ground reference.
