TPS65281RGVR Frequently Asked Questions (FAQs)

  • Texas Instruments provides a recommended layout and placement guide in the TPS65281RGVR Evaluation Module User's Guide (SLVUAE4). It's essential to follow this guide to ensure proper thermal performance, noise reduction, and signal integrity.
  • The output capacitor selection depends on the output voltage, output current, and desired transient response. TI recommends using a low-ESR ceramic capacitor with a minimum capacitance of 10uF and a voltage rating of at least 1.5 times the output voltage. Refer to the TPS65281RGVR datasheet and the TI Capacitor Selection Guide (SLVA466) for more information.
  • The TPS65281RGVR has an absolute maximum input voltage rating of 18V. However, the recommended maximum input voltage is 15V to ensure reliable operation and to prevent damage to the device.
  • The TPS65281RGVR is rated for operation up to 105°C junction temperature. However, the device's performance and reliability may degrade at high temperatures. It's essential to follow the thermal design guidelines and ensure proper heat sinking to maintain a safe operating temperature.
  • TI provides a troubleshooting guide in the TPS65281RGVR datasheet and the Power Management Troubleshooting Guide (SLVA704). Common issues can be caused by incorrect component selection, poor layout, or inadequate thermal design. Use an oscilloscope to monitor the output voltage and current, and check the device's thermal performance using a thermal camera or thermometer.
