TPS65141PWPR Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for the TPS65141PWPR to ensure optimal performance?
  A good PCB layout for the TPS65141PWPR involves placing the input capacitors close to the VIN pin, using a solid ground plane, and keeping the high-current paths short and wide. A 4-layer PCB with a dedicated power plane and a solid ground plane is recommended.
• How do I choose the right input and output capacitors for the TPS65141PWPR?
  Choose input capacitors with a voltage rating of at least 1.5 times the maximum input voltage, and output capacitors with a voltage rating of at least 1.5 times the output voltage. The capacitance value should be based on the required ripple current and output voltage ripple. X5R or X7R ceramic capacitors are recommended.
• What is the maximum ambient temperature range for the TPS65141PWPR?
  The TPS65141PWPR can operate in an ambient temperature range of -40°C to 85°C. However, the junction temperature should not exceed 150°C.
• How do I ensure the TPS65141PWPR is stable and does not oscillate?
  To ensure stability, use a minimum output capacitance of 10uF, and a maximum ESR of 1 ohm. Also, ensure that the input voltage is within the recommended range, and the output voltage is set correctly. A stable input voltage and a low-ESR output capacitor are essential for stability.
• Can I use the TPS65141PWPR in a high-reliability or automotive application?
  Yes, the TPS65141PWPR is qualified for automotive and high-reliability applications. It meets the AEC-Q100 standard for automotive applications and is suitable for use in harsh environments.
