Connectors and Jumpers Description and Placement

TPS566235EVM-036 is provided with input/output connectors and test points as listed in Table 5-1. And Figure 5-1 and Figure 5-2 shows connectors and jumpers placement on TPS566235EVM-036 board.

A power supply capable of supplying greater than 5 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 6 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. TP6 is used to monitor the output voltage with TP13 as the ground reference.
