注意事项 PRECAUTIONS

1 Input voltage range: Ensure input voltage is within DC 4.5V to 5.5V (compatible with nominal 5V input)

2 Output load limits: Do not exceed the maximum output current of 0.9A (3W/3.3V) to avoid overload

3 Derating guidelines: When ambient temperature exceeds 50°C, reduce output power according to the derating curve (e.g., natural air cooling: linear derating from 100% at 50°C to 0% at 85°C)

4 Remote On/Off operation: Follow the connection diagram to correctly wire the TRM terminal for remote power control

5 Environmental conditions: Operating temperature range is -40°C to 85°C; storage temperature range is -40°C to 125°C

6 Vibration resistance: Complies with IEC standards (10-55Hz frequency range, 0.5mm amplitude, 3 axes)

7 Safety compliance: Meets UL62368-1, CSA62368-1, and EN62368-1 safety standards for reliable operation

8 Overload protection: Auto-recovery overcurrent protection activates in case of short circuit or overload; avoid prolonged exposure to such conditions (no more than 10 seconds)

9 Cooling requirements: Ensure adequate ventilation (natural air or forced airflow) to maintain operating temperature within specified limits
