LTC4125EUFD#PBF Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and a separate layer for the high-current paths is recommended. Keep the high-current paths short and wide, and use thermal vias to connect the IC to the ground plane.
  • Monitor the IC's junction temperature, input voltage, and output current to ensure they are within the specified limits. Use thermal management techniques such as heat sinks or thermal interfaces to keep the junction temperature below 125°C.
  • A low-ESR ceramic capacitor with a value of 10uF to 22uF is recommended. The capacitor should be placed close to the VIN pin and have a voltage rating of at least 2x the maximum input voltage.
  • Choose an inductor with a low DCR, high saturation current, and a core material that can handle the switching frequency. The inductor value should be selected based on the output voltage, output current, and switching frequency.
  • A low-ESR ceramic capacitor with a value of 10uF to 47uF is recommended. The capacitor should be placed close to the VOUT pin and have a voltage rating of at least 1.5x the output voltage.
