Instructions for Using TNY268G

1. Input Voltage Range:

   • Ensure the input voltage is within the range of 70VAC to 375VAC to avoid damage to the device.

2. Output Power:

   • The TNY268G can deliver up to 14W of output power. Design your circuit to ensure this limit is not exceeded.

3. Quiescent Current:

   • The quiescent current is typically 1.0mA. This is the current drawn by the device when it is in standby mode.

4. Start-Up Current:

   • The start-up current is typically 1.5mA. This is the current required to initiate the operation of the device.

5. Operating Temperature:

   • The device can operate within a temperature range of -40°C to 125°C. Ensure the ambient temperature does not exceed these limits.

6. Storage Temperature:

   • Store the device in an environment with a temperature range of -55°C to 150°C.

7. Maximum Junction Temperature:

   • The maximum junction temperature should not exceed 150°C. Proper heat dissipation mechanisms should be implemented to prevent overheating.

8. Thermal Resistance:

   • The thermal resistance from the junction to the case is typically 2.5°C/W. Use appropriate heatsinks or cooling methods to manage heat dissipation.

9. Isolation Voltage:

   • The isolation voltage is 4000VAC. Ensure that the device is used in circuits where this isolation voltage is maintained to avoid electrical breakdown.

10. Output Voltage Regulation:

    • The output voltage regulation is ±5%. Design your circuit to accommodate this variation in output voltage.

11. Mounting and Handling:

    • Handle the device with care to avoid mechanical stress. Follow standard ESD (Electrostatic Discharge) precautions during handling and installation.

12. Soldering:

    • Use a soldering iron with a temperature no higher than 300°C and complete the soldering process within 10 seconds to prevent damage to the device.

13. Testing:

    • Before finalizing the design, test the device under various operating conditions to ensure reliable performance.

By following these guidelines, you can ensure optimal performance and longevity of the TNY268G in your application.
