Instructions for TOP204YN:

1. Input Connection:

   • Connect the AC input to the designated pins on the TOP204YN.
   • Ensure the input voltage is within the specified range (170VAC to 375VAC).

2. Output Connection:

   • Connect the load to the output pins.
   • The output voltage is typically 5.0VDC with a maximum current of 1.2A.

3. Heat Dissipation:

   • Ensure adequate heat dissipation by mounting the TOP204YN on a heatsink or a PCB with sufficient copper area.
   • The operating temperature range is -40°C to 85°C.

4. No-Load Operation:

   • The no-load input power is typically 0.15W, which is low but should be considered in low-power applications.

5. Storage Conditions:

   • Store the device in a dry environment with humidity between 0% and 95% (non-condensing).
   • The storage temperature range is -40°C to 125°C.

6. Electromagnetic Compatibility (EMC):

   • Follow good PCB layout practices to minimize electromagnetic interference (EMI).
   • Use appropriate filtering components if necessary.

7. Safety Considerations:

   • Ensure all connections are secure and insulated to prevent electrical shock.
   • Follow local and international safety standards for power supply design.

8. Testing and Troubleshooting:

   • Test the output voltage and current under various load conditions to ensure proper operation.
   • Check the input and output connections for any loose or damaged wires.

9. MTBF:

   • The MTBF of 1,000,000 hours indicates a high reliability, but regular maintenance and inspection are recommended for long-term use.
