MAX38643AENT+T Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the analog and digital grounds separate and connect them at a single point. Use a low-ESR capacitor for the input and output capacitors.
  • To ensure stability, use a minimum output capacitance of 10uF, and ensure the output capacitor has a low ESR. Also, avoid using ceramic capacitors with high ESL, as they can cause oscillations.
  • The maximum input voltage is 5.5V, but it's recommended to keep the input voltage below 5V to ensure reliable operation and to prevent damage to the device.
  • The output voltage can be programmed using the FB pin. Connect a resistive divider from the output voltage to the FB pin, and adjust the resistor values to set the desired output voltage.
  • The device has a thermal derating of 6.4mW/°C above 25°C. Ensure good thermal design and heat sinking to prevent overheating and reduce the risk of thermal shutdown.
