Design Notes
Place the TPS82130SILR close to the load to minimize parasitic inductance and resistance. Use a solid ground plane and connect the thermal pad to a large copper area for heat dissipation. Ensure input and output capacitors are placed as close as possible to the VIN and VOUT pins, respectively, with short, wide traces.
At 3A output, the power dissipation can be significant. For example, at 12V input and 3.3V output, the efficiency is around 90%, so power loss is approximately 1W. The uSIP package has a thermal resistance of about 20C/W (theta_JA) with proper PCB copper. Ensure adequate copper area and airflow to keep the junction temperature below 125C.
Do not exceed the absolute maximum input voltage of 17V. Use a 10uF ceramic capacitor on the input and a 22uF ceramic capacitor on the output as recommended in the datasheet. The feedback resistor divider should use 1% tolerance resistors to maintain output voltage accuracy. Avoid routing sensitive analog traces near the SW node to prevent noise coupling.
