TPS65231A2DCAR Frequently Asked Questions (FAQs)

  • Texas Instruments provides a recommended PCB layout in the TPS65231A2DCAR evaluation module (EVM) user's guide, which can be found on the TI website. The EVM user's guide includes a detailed layout guide, including component placement, routing, and thermal considerations.
  • To optimize the output voltage ripple, ensure that the output capacitors are properly selected and placed close to the output pins. Additionally, use a low-ESR capacitor and consider adding a ceramic capacitor in parallel to reduce the output voltage ripple. The TPS65231A2DCAR datasheet provides guidance on output capacitor selection and placement.
  • The TPS65231A2DCAR has an absolute maximum input voltage rating of 18V. However, the recommended operating input voltage range is 6.5V to 14V. Operating the device above the recommended input voltage range may affect its performance and reliability.
  • The TPS65231A2DCAR has a built-in overvoltage protection (OVP) feature that can be enabled by connecting the OVP pin to a voltage divider network. The OVP threshold can be set by selecting the appropriate resistor values. The TPS65231A2DCAR datasheet provides guidance on implementing OVP.
  • The TPS65231A2DCAR has a thermal derating curve that can be found in the datasheet. The device's power dissipation capability decreases as the ambient temperature increases. The thermal derating curve provides guidance on the maximum power dissipation at different ambient temperatures.
