PM6641TR Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a dedicated thermal layer and a solid ground plane is recommended. Ensure a minimum of 2 oz copper thickness and a thermal relief pattern under the device.
  • Implement a robust thermal management system, including a heat sink and thermal interface material. Ensure good airflow and avoid thermal hotspots.
  • Use X7R or X5R ceramic capacitors with a voltage rating of 10V or higher. For input capacitors, use 10uF to 22uF values, and for output capacitors, use 4.7uF to 10uF values.
  • Enable the low-power mode by setting the EN pin low. Ensure that all unnecessary circuits are disabled, and use a low-dropout linear regulator for the standby voltage.
  • Keep the switching node (SW) away from sensitive analog circuits. Use a star-ground configuration, and ensure that the input and output capacitors are placed close to the device.
