1.1 Before You Begin

The following warnings and cautions are noted for the safety of anyone using or working close to the TPS54A20EVM-770. Observe all safety precautions.

GUID-B1793315-3BAB-4409-8861-589F6F96471D-low.pngWarningThe TPS54A20EVM-770 circuit module may 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 may result in exposed voltages, hot surfaces or sharp edges. Do not reach under the board during operation.

CAUTION:

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

CAUTION:

Some power supplies can be damaged by application of external voltages. If using more than 1 power supply, check your equipment requirements and use blocking diodes or other isolation techniques, as needed, to prevent damage to your equipment.
