LTC4267IGN-1#PBF Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the input and output traces short and away from each other, and use a common mode choke to filter the input.
  • Monitor the junction temperature (TJ) and ensure it stays below the maximum rating of 150°C. Also, keep the input voltage and current within the recommended limits, and ensure proper heat sinking and thermal management.
  • A low-ESR ceramic capacitor (e.g., X5R or X7R) with a value of 10uF to 22uF is recommended. The input capacitor affects the converter's stability, transient response, and noise performance.
  • Use the datasheet's recommended feedback network values as a starting point, and then adjust the resistors and capacitors to achieve the desired output voltage and stability. A good starting point is to use a resistive divider with a ratio of 1:1 to 1:2.
  • Select an inductor with a high saturation current rating, low DC resistance, and a suitable inductance value (e.g., 1uH to 10uH). The inductor affects the converter's efficiency, output voltage ripple, and transient response.
