Instructions for Use:

1. Input Connection:

   • Connect the input voltage between the VIN and GND pins. Ensure the input voltage is within the specified range of 3.5V to 60V.

2. Output Configuration:

   • Adjust the output voltage using external resistors connected to the FB pin according to the datasheet formula.
   • The output voltage can be set anywhere between 0.8V and the input voltage minus 2V.

3. Capacitors:

   • Place a ceramic capacitor close to the VIN and GND pins for stability and noise reduction.
   • Add an output capacitor between VOUT and GND as recommended in the datasheet for proper operation.

4. Inductor Selection:

   • Choose an inductor value based on the desired output current and ripple specifications provided in the datasheet.

5. Protection:

   • The device includes built-in overcurrent and thermal protection. No additional components are required for these features.

6. Thermal Considerations:

   • Ensure adequate heat dissipation if operating near the maximum junction temperature of 125°C.

7. Layout Recommendations:

   • Follow good PCB layout practices, minimizing trace lengths for high-frequency signals and ensuring proper grounding to reduce electromagnetic interference.

For detailed design considerations and specific application circuits, refer to the complete datasheet available from the manufacturer.
