Instructions for Use

  1. Power Supply Connection:

    • Connect the input power supply to the IN pin.
    • Connect the ground (GND) to the GND pin.
  2. Output Voltage Setting:

    • The output voltage can be adjusted by connecting a voltage divider between the OUT and FB pins. The formula to calculate the output voltage is: [ V_{text} = V_{text} times left(1 + fracright) ] where ( V_{text} ) is typically 1.23V.
  3. Enable Control:

    • The EN pin controls the enable/disable function of the converter. Apply a high signal (e.g., 3.3V or 5V) to enable the converter, and a low signal (e.g., 0V) to disable it.
  4. Power Good Output:

    • The PG pin indicates whether the output voltage is within the regulation range. It outputs a high signal when the output is stable and within the specified range.
  5. Inductor Selection:

    • Choose an inductor with a suitable inductance value and current rating to match the switching frequency and output current requirements. A typical inductance value is 4.7渭H.
  6. Capacitor Selection:

    • Use ceramic capacitors for input and output filtering. Recommended values are 10渭F for the input capacitor and 22渭F for the output capacitor.
  7. Thermal Management:

    • Ensure proper thermal management by providing adequate PCB copper area for heat dissipation. The device should not exceed its maximum operating temperature.
  8. Layout Considerations:

    • Place the input and output capacitors as close as possible to the respective pins to minimize parasitic inductance and improve stability.
    • Keep the traces for high-frequency signals short and direct to reduce noise and interference.
  9. Testing:

    • Before finalizing the design, test the converter under various load conditions to ensure it meets the required performance specifications.
  10. Safety Precautions:

    • Ensure that the input and output voltages are within the specified ranges to avoid damage to the device.
    • Follow all relevant safety guidelines and standards when handling and testing the device.
