VN750STR-E datasheet by STMicroelectronics

VN750STR-E Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  STMicroelectronics recommends a 2-layer PCB with a thermal pad connected to a large copper area on the bottom layer to dissipate heat efficiently.
• How do I ensure reliable operation in high-temperature environments?
  Use a heat sink with a thermal resistance of 10°C/W or lower, and ensure good airflow around the device. Also, consider derating the device's current handling capability at high temperatures.
• What is the recommended input capacitor value and type for optimal performance?
  A 10uF to 22uF X7R or X5R ceramic capacitor is recommended, with a voltage rating of 25V or higher, placed as close to the VIN pin as possible.
• How do I minimize electromagnetic interference (EMI) in my design?
  Use a shielded cable for the output, keep the input and output traces separate, and add a common-mode choke or ferrite bead to the output to reduce EMI.
• What is the maximum allowed voltage drop across the device?
  The maximum allowed voltage drop is 0.5V, but it's recommended to keep it below 0.3V to ensure reliable operation and minimize power loss.
