2.1 Input/Output Connections

The TPS568215EVM-762 is provided with input/output connectors and test points as shown in Table 2-1. A power supply capable of supplying greater than 4 A must be connected to J1 through a pair of 20-AWG wires or better. The load must be connected to J2 through a pair of 20-AWG wires or better. The maximum load current capability is 8 A. Wire lengths must be minimized to reduce losses in the wires. Test point TP1 provides a place to monitor the VIN input voltages with TP2 providing a convenient ground reference. TP9 is used to monitor the output voltage with TP10 as the ground reference.
