Instructions for Use

1. Power Supply Connection:

   • Connect the input power supply to the VIN and GND pins.
   • Ensure the input voltage is within the specified range (2.7V to 15V).

2. Output Configuration:

   • Adjust the output voltage using an external resistor divider network connected to the FB (Feedback) pin.
   • The output voltage can be calculated using the formula: VOUT = 1.23V * (1 + R1/R2), where R1 and R2 are the resistors in the feedback network.

3. Capacitor Selection:

   • Use a low ESR ceramic capacitor (10渭F to 100渭F) on the input side to ensure stable operation.
   • Use a low ESR ceramic capacitor (10渭F to 100渭F) on the output side to filter the output voltage.

4. Inductor Selection:

   • Choose an inductor with a saturation current rating higher than the maximum output current (3A).
   • A typical inductor value is 4.7渭H to 10渭H.

5. Thermal Management:

   • Ensure adequate heat dissipation by providing a good thermal path to the PCB or using a heatsink if necessary.
   • Monitor the device temperature to avoid exceeding the maximum operating temperature.

6. Protection Circuits:

   • The OZ960S includes built-in overcurrent, overvoltage, and thermal protection features.
   • In case of a fault, the device will automatically shut down and restart after the fault condition is cleared.

7. Layout Considerations:

   • Keep the input and output capacitors as close as possible to the IC to minimize parasitic inductance.
   • Use wide traces for power paths to reduce resistance and improve efficiency.

8. Testing:

   • After assembly, test the circuit under various load conditions to ensure it meets the desired performance specifications.
   • Verify the output voltage stability and efficiency.

9. Storage:

   • Store the device in a dry, cool place to prevent moisture damage.
   • Handle with care to avoid static discharge, which can damage the sensitive components.
