The TPS542A52EVM-059 evaluation module (EVM) uses the Texas Instruments TPS542A52 buck converter. The TPS542A52 is a highly integrated high-efficiency synchronous buck converter with differential remote sensing. It is capable of delivering up to 15 A to a load with output voltages ranging from 0.5 V to 5.5 V. The high-side and low-side switching MOSFETs are integrated in the device package, along with their associated gate drive circuitry.
High efficiency, wide-operating junction temperature, and high output voltage accuracy make the TPS542A52 an excellent choice for applications where high output voltage accuracy across rigorous thermal conditions are required. The rated input voltage, output voltage, and output current range for the TPS542A52 are given in Table 1-1.
CONVERTER PART NUMBER | INPUT VOLTAGE RANGE | OUTPUT VOLTAGE RANGE | OUTPUT CURRENT RANGE |
---|---|---|---|
TPS542A52 | 4 V to 18 V | 0.5 V to 5.5 V | 0 A to 15 A |
The following warnings and cautions are noted for the safety of anyone using or working close to the TPS542A52EVM-059. Observe all safety precautions.
![]() | Warning | The TPS542A52EVM-059 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.
