1.1 Before You Begin

The following warnings and cautions are noted for the safety of anyone using or working close to the TPS546C20AEVM2-746. Observe all safety precautions.

GUID-B1793315-3BAB-4409-8861-589F6F96471D-low.pngWarningThe TPS546C20AEVM2-746 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.
GUID-0B757A9E-615A-487A-9F6D-4DE8EA54532B-low.gifCautionDo 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, or sharp edges. Do not reach under the board during operation.

CAUTION:

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

CAUTION:

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

CAUTION:

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