TPS22991BRAAR Frequently Asked Questions (FAQs)

  • Texas Instruments provides a recommended PCB layout in the datasheet, but it's also recommended to follow general high-frequency PCB design guidelines, such as keeping the power traces short and wide, using a solid ground plane, and minimizing vias and thermal reliefs.
  • The TPS22991BRAAR has a thermal pad on the bottom of the package, which should be connected to a solid ground plane on the PCB to dissipate heat. Additionally, ensure good airflow around the device and consider using a heat sink if the device is expected to operate at high temperatures or high currents.
  • The TPS22991BRAAR can drive capacitive loads up to 10nF, but it's recommended to limit the capacitive load to 4.7nF or less to ensure stable operation. Exceeding this limit may cause oscillations or instability in the output voltage.
  • The TPS22991BRAAR is rated for operation up to 125°C, but it's recommended to derate the output current and voltage at high temperatures to ensure reliable operation. Consult the datasheet for specific derating guidelines.
  • Start by checking the PCB layout and ensuring that it follows the recommended layout guidelines. Verify that the input voltage and current are within the specified limits, and check for any signs of overheating or thermal stress. Use an oscilloscope to monitor the output voltage and current, and consult the datasheet for troubleshooting guidelines specific to the TPS22991BRAAR.
