LTM4647EY#PBF Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and thermal vias is recommended. Keep the thermal pad connected to the ground plane to improve heat dissipation.
  • Monitor the input voltage, output current, and junction temperature to ensure they are within the specified limits. Use the thermal shutdown feature to prevent overheating.
  • A low-ESR ceramic capacitor (e.g., X5R or X7R) with a value of 10uF to 22uF is recommended to filter the input voltage and reduce noise.
  • Use a high-precision voltage reference, ensure the output voltage sense lines are properly routed, and minimize noise and interference on the output voltage sense lines.
  • The maximum output current derating is 10% per 10°C above 25°C. This means the maximum output current will decrease by 10% for every 10°C increase in junction temperature above 25°C.
