The BSR054EVM evaluation module uses the TPS543C20AEVM-054 device. The TPS543C20AEVM-054 is a highly integrated synchronous buck converter that is designed for up to 40-A current output.
The following warnings and cautions are noted for the safety of anyone using or working close to the TPS543C20AEVM-054. Observe all safety precautions.
![]() | Warning | The TPS543C20AEVM-054 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. |
![]() |
Caution | Do not leave the EVM powered when unattended. |
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.
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.
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.
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.
The BSR054EVM is designed as a single output DC/DC converter that demonstrates the TPS543C20AEVM-054 in a typical low-voltage application while providing a number of test points to evaluate the performance. It uses a nominal 12-V input bus to produce a regulated 0.9-V output at up to 40-A load current.
