LTC2937MPUHE#PBF Frequently Asked Questions (FAQs)

  • A good PCB layout for the LTC2937 involves keeping the input and output capacitors close to the IC, using a solid ground plane, and minimizing the length of the traces between the IC and the capacitors. A 4-layer PCB with a dedicated power plane and a solid ground plane is recommended.
  • Choose X5R or X7R ceramic capacitors with a voltage rating of at least 2x the maximum input voltage. The capacitance value should be at least 10uF for the input capacitor and 22uF for the output capacitor. The ESR of the capacitors should be less than 100mΩ.
  • The maximum ambient temperature range for the LTC2937 is -40°C to 125°C. However, the junction temperature should not exceed 150°C.
  • Yes, the LTC2937 is qualified for automotive and high-reliability applications. It meets the requirements of AEC-Q100 and is manufactured in an automotive-qualified facility.
  • Check the PCB layout, ensure that the input and output capacitors are properly connected, and verify that the input voltage is within the recommended range. Also, check for any noise or interference on the input or output lines. If the issue persists, consult the datasheet and application notes or contact Analog Devices' technical support.
