Instructions for Use

1. Power Supply Connection:

   • Connect the input voltage (V_IN) between 85V and 265V AC/DC to the input terminals of the TNY279GN.
   • Ensure proper grounding for stable operation.

2. Output Configuration:

   • The device is designed to provide a regulated output voltage of 5V. No external components are required for basic operation.

3. Load Requirements:

   • The load regulation ensures minimal change in output voltage with varying loads within specified limits.

4. Thermal Management:

   • Ensure adequate heat dissipation if operating at high temperatures or under heavy loads. Monitor the operating temperature to avoid exceeding 85°C.

5. Protection Mechanisms:

   • The TNY279GN includes built-in protection against overload, short circuits, and thermal issues. In case of a fault, the device will automatically shut down to prevent damage.

6. Efficiency Considerations:

   • For optimal efficiency, operate within the recommended input voltage range and load conditions. Typical efficiency ranges from 70% to 90%.

7. Switching Frequency:

   • The internal switching frequency is set at 65kHz, which helps minimize electromagnetic interference (EMI).

8. Storage and Handling:

   • When not in use, store the device in an environment where the temperature does not exceed 150°C or drop below -55°C.

For detailed specifications and additional information, refer to the official datasheet provided by the manufacturer.
