2.1 Input/Output Connections
The TPS54010EVM-067 is provided with input/output connectors and test
points as shown in Table 2−1. Connect a power supply capable of supplying
12 A to J1 through a pair of 14 AWG wires. Connect a power supply capable
of supplying 25 mA to J2 through a pair of 22 AWG wires. Connect the load
to J3 through a pair of 14 AWG wires. The maximum load current capability
is 14 A. Minimize wire lengths to reduce losses in the wires. Test points TP1
and TP2 provide a place to monitor the the PVIN and VIN input voltages wth
TPS providing a convenient ground reference. Use TP7 to monitor the output
voltage with TP8 as the ground reference.
