Input and Output Connections

The TPSM863252EVM 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 the TPSM863252EVM board.

A power supply capable of supplying 3 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 3 A. Wire lengths must be minimized to reduce losses in the wires. The TP1 provides a place to monitor the VIN input voltages with TP2 providing a convenient ground reference. TP3 is used to monitor the output voltage with TP4 as the ground reference.
