SLUUCG8A June 2022 – August 2022 TPS51383
The TPS51383EVM and TPS51383EVM are provided with input and output connectors and test points as shown in the following table. A power supply capable of supplying 8 A must be connected 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. Wire lengths must be minimized 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.
