Instructions for Use:

1. Input Connection: Connect the input terminals to the AC power source within the specified voltage range (180VAC to 265VAC).
2. Output Configuration: Ensure the output is configured to provide the desired regulated DC voltage (5.0VDC). The output should be capable of supplying up to 1.0A continuously.
3. Heat Management: The device can dissipate up to 1.0W of power. Ensure adequate heat sinking to keep the junction temperature below 150°C, especially under high ambient temperatures.
4. Operating Environment: The device operates reliably within a temperature range of -40°C to 85°C. Store the device in an environment where the temperature does not exceed -65°C to 150°C.
5. Switching Frequency: The typical switching frequency is 132kHz, which helps in reducing the size of external components such as inductors and capacitors.
6. Efficiency: The typical efficiency at full load is 85%, which is a balance between performance and thermal management.
7. Safety Precautions: Ensure proper insulation and grounding to prevent electrical hazards. Follow all relevant safety standards and guidelines when designing and testing circuits using this component.
