Instructions for Use:

1. Input Connection:

   • Connect the input voltage within the specified range (4.5V to 28V) to the VIN and GND pins.

2. Output Configuration:

   • Set the desired output voltage using an external resistor divider network connected to the FB pin.
   • Ensure the output voltage is within the adjustable range of 0.9V to 14V.

3. Inductor Selection:

   • Choose an inductor value that provides stable operation based on the switching frequency (650kHz) and output current requirements.

4. Capacitor Requirements:

   • Use appropriate input and output capacitors to ensure stability and minimize ripple. Refer to the datasheet for recommended capacitor values.

5. Protection:

   • The device includes built-in overcurrent protection, thermal shutdown, and undervoltage lockout. Ensure these features are not triggered by operating conditions outside the specified limits.

6. PCB Layout Considerations:

   • Place the input and output capacitors as close as possible to the IC to reduce noise and improve transient response.
   • Keep the high-current paths short and wide to minimize losses and heating.

7. Operating Environment:

   • Operate the device within the temperature range of -40°C to +85°C to ensure reliable performance.

8. Handling Precautions:

   • Handle with care to avoid damage to the sensitive components. Follow ESD precautions when handling the device.
