2.3 Best Practices

The following warnings and cautions are noted for the safety of anyone using or working close to the TPS543B25T. Observe all safety precautions.

CAUTION:
GUID-760FFF33-81B2-40E5-B062-2F012CADAFF1-low.gif

The TPS543B25T can become hot during operation due to dissipation of power in some operating conditions. Avoid contact with the board. Follow all applicable safety procedures applicable to your laboratory.

Caution: Hot surface.

Contact can cause burns.

Do not touch!
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:

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