SLUUCN0B june 2022 – august 2023 TPS51386
The TPS51386EVM is provided with input and output connectors and test points as shown in Table 4-1. Connect a power supply capable of supplying 8 A to J1 through a pair of 20AWG wires. The load must be connected to J2 through a pair of 20AWG wires. The maximum load current capability is 8 A. Minimize wire lengths to reduce losses in the wires. Test point TP2 provides a place to monitor the VIN input voltages with TP9 providing a convenient ground reference. TP5 is used to monitor the output voltage with TP12 as the ground reference.
