The recommended layout for the TPS3513N involves placing the input capacitor (CIN) close to the VIN pin, and the output capacitor (COUT) close to the VOUT pin. The power traces should be wide and short, and the ground plane should be solid and unbroken. Additionally, the device should be placed away from high-current carrying traces and noise sources.
The input capacitor (CIN) should have a low ESR and be rated for the input voltage. A ceramic capacitor with a value of 1-10uF is recommended. The output capacitor (COUT) should have a low ESR and be rated for the output voltage. A ceramic capacitor with a value of 1-22uF is recommended. The capacitor values can be adjusted based on the specific application requirements.
The TPS3513N can handle a maximum input voltage of 15V. However, it is recommended to operate the device within the specified input voltage range of 2.7V to 12V to ensure optimal performance and reliability.
The TPS3513N is rated for operation up to 125°C. However, the device's performance and reliability may degrade at high temperatures. It is recommended to derate the device's output current and voltage at high temperatures to ensure reliable operation.
To troubleshoot issues with the TPS3513N, start by checking the input voltage and current, and the output voltage and current. Verify that the device is properly connected and that the input and output capacitors are properly sized. Check for any signs of overheating, such as excessive temperature or thermal shutdown. Use an oscilloscope to check for any noise or oscillations on the input or output.
