2.1 Input/Output Connections

The TPS54J060EVM-067 and TPS54J061EVM-067 are provided with input/output connectors and test points as shown in Table 2-1. A power supply capable of supplying 6 A must be connected to J1 through a pair of 20-AWG or higher wires. The load must be connected to J2 through a pair of 20-AWG or higher wires. The maximum load current capability is 6-A.

Wire lengths must be minimized to reduce losses in the wires. VIN_SNS+ provides a place to monitor the VIN input voltages with VIN_SNS- providing a convenient ground reference. VOUT is used to monitor the output voltage with PGND as the ground reference.
