LTC4365CDDB#PBF datasheet by Linear Technology

LTC4365CDDB#PBF Frequently Asked Questions (FAQs)

• What is the maximum voltage rating for the input pins?
  The maximum voltage rating for the input pins (VIN, VCC) is 36V, but it's recommended to keep it below 30V for reliable operation.
• How do I ensure the overvoltage protection (OVP) threshold is accurate?
  To ensure accurate OVP threshold, make sure to decouple the VIN pin with a 1uF ceramic capacitor to GND, and keep the VIN pin quiet during startup.
• What is the recommended layout for the LTC4365CDDB#PBF?
  For optimal performance, follow a star-ground layout, keep the input and output capacitors close to the IC, and use a separate ground plane for the analog and digital sections.
• Can I use the LTC4365CDDB#PBF in a high-temperature environment?
  Yes, the LTC4365CDDB#PBF is rated for operation up to 125°C, but ensure proper thermal management and derate the maximum junction temperature accordingly.
• How do I troubleshoot the LTC4365CDDB#PBF if it's not functioning as expected?
  Check the input voltage, output voltage, and current sense resistor values. Verify the correct configuration of the EN, UV, and OVP pins. Use an oscilloscope to monitor the input and output waveforms.
