Instructions:

1. Input Connection: Connect the input voltage between the VIN and GND pins. Ensure the input voltage is within the specified range.
2. Output Configuration: Adjust the output voltage using an external resistor network connected to the FB pin as per the datasheet formula.
3. Capacitor Selection: Choose input and output capacitors that meet the stability criteria outlined in the datasheet to ensure proper operation.
4. Thermal Considerations: For optimal thermal performance, ensure adequate PCB layout and heat dissipation methods are implemented.
5. Switching Frequency Adjustment: If frequency adjustment is required, use an external resistor on the RT pin.
6. Testing and Validation: After assembly, validate the output voltage and efficiency under various load conditions to ensure compliance with design specifications.
