Instructions for BD3401KS2

1. Input Voltage (V_IN):

   • Ensure the input voltage is within the range of 4.5V to 30V.
   • Avoid exceeding the maximum input voltage to prevent damage to the device.

2. Output Voltage (V_OUT):

   • Set the output voltage within the range of 1.8V to 15V.
   • Use external resistors to adjust the output voltage if necessary.

3. Output Current (I_OUT):

   • The device can provide a typical output current of 1.5A and a maximum of 3A.
   • Ensure the load does not exceed the maximum output current to avoid overheating.

4. Efficiency:

   • The efficiency is typically 90% under the condition of V_IN = 12V, V_OUT = 5V, and I_OUT = 1A.
   • Optimize the input and output conditions to achieve the best efficiency.

5. Dropout Voltage:

   • The dropout voltage is typically 1.2V at I_OUT = 3A and V_OUT = 5V.
   • Ensure the input voltage is at least 1.2V higher than the output voltage to maintain regulation.

6. Quiescent Current:

   • The quiescent current is typically 1.5mA when V_IN = 12V, V_OUT = 5V, and I_OUT = 0A.
   • This current is drawn even when there is no load on the output.

7. Load Regulation:

   • The load regulation is 卤1% over the range of 0 to 3A.
   • This ensures that the output voltage remains stable despite changes in the load.

8. Line Regulation:

   • The line regulation is 卤1% over the input voltage range of 4.5V to 30V.
   • This ensures that the output voltage remains stable despite variations in the input voltage.

9. Ripple Rejection:

   • The ripple rejection is 70dB at 100Hz.
   • This helps in filtering out noise from the input power supply.

10. Operating Temperature Range:

    • The device can operate within a temperature range of -40掳C to 125掳C.
    • Ensure proper heat dissipation to avoid overheating, especially at high output currents.

11. Storage Temperature Range:

    • The device can be stored within a temperature range of -55掳C to 150掳C.
    • Avoid exposing the device to extreme temperatures for extended periods.

12. Mounting and PCB Layout:

    • Use a good thermal design to ensure efficient heat dissipation.
    • Place the device away from heat sources and ensure adequate airflow.
    • Use a ground plane and keep the input and output capacitors close to the device to minimize noise and improve stability.

13. Capacitors:

    • Use appropriate input and output capacitors to stabilize the voltage and reduce ripple.
    • Recommended values are typically 10渭F for the input and 10渭F for the output, but these can vary based on specific application requirements.

14. Protection Features:

    • The device includes overcurrent protection and thermal shutdown to prevent damage under fault conditions.
    • Ensure that the load does not exceed the maximum ratings to avoid triggering these protections.
