LTC1955EUH#PBF Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and a separate analog ground plane is recommended. Keep the analog and digital grounds separate and connect them at a single point. Use a low-ESR capacitor for the input and output capacitors.
  • To ensure stability, ensure that the output capacitor has a low ESR, the input capacitor is properly sized, and the feedback resistors are properly selected. Also, avoid using a capacitor with a high ESL (Equivalent Series Inductance) in the output filter.
  • The maximum input voltage that the LTC1955EUH can handle is 15V. Exceeding this voltage may damage the device.
  • The LTC1955EUH is rated for operation from -40°C to 125°C. However, the device's performance may degrade at high temperatures. Ensure that the device is properly heat-sinked and that the operating temperature is within the specified range.
  • To troubleshoot issues, check the input voltage, output voltage, and feedback resistors. Ensure that the device is properly soldered and that there are no shorts or opens on the PCB. Use an oscilloscope to check for oscillations or noise on the output.
