2.2 Best Practices

The following warnings and cautions are noted for the safety of anyone using or working close to the TPS546C25EVM-1PH. Observe all safety precautions.

TPS546C25EVM-1PH Caution Hot surface. Contact can cause burns. Do not touch! TPS546C25EVM-1PH circuit module can become hot during operation due to dissipation of heat. Avoid contact with the board. Follow all applicable safety procedures applicable to your laboratory.
TPS546C25EVM-1PH Caution Do not leave the EVM powered when unattended.
WARNING:

The circuit module has signal traces, components, and component leads on the bottom of the board. This can result in exposed voltages, hot surfaces, and sharp edges. Do not reach under the board during operation.

WARNING:

External Connections: All external connections to the hardware must stay within the recommended operating conditions and intended usage for all hardware/components connected in the system.

CAUTION:

The circuit module can be damaged by over temperature. To avoid damage, monitor the temperature during evaluation and provide cooling.

CAUTION:

Some power supplies can be damaged by application of external voltages. If using more than one power supply, check your equipment requirements and use blocking diodes or other isolation techniques, to prevent damage to the equipment.

CAUTION:

The communication interface is not isolated on the EVM. Make sure that there is no ground potential between the computer and the EVM. Be aware that the computer is referenced to the battery potential of the EVM.
