LTM8078IY#PBF Frequently Asked Questions (FAQs)

  • A 2-layer or 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.
  • Choose a low-ESR ceramic or polymer capacitor with a value of 10uF to 47uF, depending on the output voltage and current requirements. Ensure the capacitor's voltage rating is higher than the output voltage.
  • Keep the high-current paths short and wide, using thick copper traces (e.g., 1 oz or 2 oz) to minimize resistance and inductance. Avoid sharp corners and use rounded traces to reduce electromagnetic interference (EMI).
