注意事项 PRECAUTIONS

1 Ensure input voltage remains within the specified 18-72V range to avoid damage

2 Connect a 10uF capacitor to the output terminal to achieve rated ripple and noise performance

3 Follow the free air convection derating curve: reduce output power when ambient temperature exceeds 85°C

4 Resolve short circuits promptly even though continuous protection is available

5 Verify pinout details before substituting with other pin-compatible converters

6 Store in an environment with temperature -40°C to +125°C and humidity ≤95% (non-condensing)

7 Adhere to IEC 60950-1 safety guidelines during integration

8 Do not exceed maximum case temperature of 100°C under full load

9 Ensure adequate airflow for free air convection cooling
