NCP1237BD65R2G Frequently Asked Questions (FAQ)

  • The recommended PCB layout for optimal thermal performance involves placing the device on a thermal pad connected to a large copper area on the PCB, and ensuring good airflow around the device. A minimum of 2oz copper thickness is recommended.

  • To ensure reliable startup, ensure that the input voltage rises monotonically and does not droop during startup. Also, ensure that the input capacitor is properly sized to handle the inrush current during startup.

  • The maximum allowed voltage on the EN pin is 6V. Exceeding this voltage may damage the device.

  • Yes, the NCP1237BD65R2G is rated for operation up to 150°C. However, the device's performance and reliability may degrade at high temperatures, so ensure that the device is properly derated and that the application is designed to accommodate the reduced performance.

  • To troubleshoot issues with the device's overcurrent protection, check the input voltage, output current, and sense resistor values to ensure they are within the recommended specifications. Also, verify that the sense resistor is properly connected and that there are no shorts or opens in the circuit.
