TPS62177DQCT Frequently Asked Questions (FAQ)

  • A good PCB layout for the TPS62177DQCT involves placing the input and output capacitors close to the device, using a solid ground plane, and minimizing the loop area of the power traces to reduce EMI.

  • To ensure stability, it's essential to follow the recommended component values and PCB layout guidelines. Additionally, ensure that the output capacitor has a low ESR and the input capacitor has a high ripple current rating.

  • The TPS62177DQCT is rated for operation up to 85°C ambient temperature. However, it's recommended to derate the output current and ensure good airflow to maintain a safe junction temperature.

  • While it's possible to use a different inductor value or type, it's not recommended as it may affect the converter's performance, efficiency, and stability. It's best to use the recommended inductor values and types to ensure optimal performance.

  • To troubleshoot issues, start by verifying the input voltage, output voltage, and current. Check the PCB layout and component values against the recommended values. Use an oscilloscope to check for oscillations or ringing on the output voltage and current waveforms.
