Instructions for Using FAN2514S33X:

  1. Input Voltage (VIN):

    • Ensure the input voltage is within the range of 4.5V to 16V.
    • Use appropriate input filtering capacitors to stabilize the input voltage.
  2. Output Voltage (VOUT):

    • The output voltage can be set using a feedback resistor divider connected to the FB pin.
    • Calculate the resistor values using the formula: VOUT = VREF * (1 + R1/R2), where VREF is typically 0.8V.
  3. Switching Frequency (fSW):

    • The switching frequency is fixed at 600kHz.
    • This helps in selecting the appropriate inductor and capacitor values for the output filter.
  4. Quiescent Current (IQ):

    • The quiescent current is typically 1.2mA at 5V input with no load.
    • This value should be considered when designing the power supply for low-power applications.
  5. Load Regulation:

    • The load regulation is 0.5% over the load range from 10mA to 1A.
    • Ensure that the load does not exceed 1A to maintain the specified performance.
  6. Line Regulation:

    • The line regulation is 0.1% per volt over the input voltage range from 4.5V to 16V.
    • This ensures stable output voltage even with variations in input voltage.
  7. Dropout Voltage (VDROPOUT):

    • The dropout voltage is typically 0.3V at 1A output current and 5V input.
    • This parameter is crucial for low-voltage applications where the input and output voltages are close.
  8. Soft-Start Time (tSS):

    • The soft-start time is typically 2ms.
    • This helps in reducing inrush current and stress on the components during startup.
  9. Thermal Shutdown Temperature (TSD):

    • The device will shut down if the temperature exceeds 160°C.
    • Ensure proper heat dissipation and cooling to prevent thermal shutdown.
  10. Short-Circuit Protection:

    • The device has built-in short-circuit protection with auto-restart functionality.
    • In case of a short circuit, the device will automatically restart after a hiccup delay.

Additional Notes:

  • Always refer to the datasheet for detailed information and specific application notes.
  • Proper PCB layout and component selection are crucial for optimal performance and reliability.
