NCV70517MW002R2G Frequently Asked Questions (FAQs)

  • A 2-layer or 4-layer PCB with a solid ground plane and thermal vias is recommended. The device should be placed near a thermal pad or a heat sink to dissipate heat efficiently.
  • Use a shielded enclosure, keep the device away from antennas and high-frequency sources, and ensure proper grounding and decoupling of the device. Follow onsemi's EMC guidelines for more information.
  • The maximum allowed voltage on the input pins is 6.5V, which is the absolute maximum rating. However, it's recommended to keep the input voltage below 5.5V for reliable operation.
  • The NCV70517MW002R2G is rated for operation up to 150°C. However, the device's performance and reliability may degrade at high temperatures. Consult onsemi's application notes for thermal management guidelines.
  • Check the input voltage, output load, and PCB layout for any issues. Verify that the device is properly decoupled and that the output capacitor is of sufficient value. Consult onsemi's application notes for troubleshooting guidelines.
