4.1 Input and Output Connections

The TPS562242EVM is provided with input and output connectors and test points as shown in Table 4-1. Figure 4-1 shows connectors and jumpers placement on TPS562242EVM board.

A power supply capable of supplying 2 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 2 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 TP6 providing a convenient ground reference. TP3 is used to monitor the output voltage with TP10 as the ground reference.
