Instructions for Using FAN5068MP

1. Input Voltage (VIN):

   • Ensure the input voltage is within the range of 2.7V to 5.5V.
   • Use appropriate decoupling capacitors (typically 10μF ceramic) close to the input pins to stabilize the input voltage.

2. Output Voltage (VOUT):

   • The output voltage is fixed at 3.3V. No external components are required to set this voltage.

3. Output Current (IOUT):

   • The device can deliver up to 3.0A of output current, with a typical output current of 1.5A.
   • Ensure proper heat dissipation if operating at high currents to avoid thermal shutdown.

4. Quiescent Current (IQ):

   • The quiescent current is typically 40μA. This is the current consumed by the device when it is active but not delivering any load current.

5. Shutdown Current (ISD):

   • When the device is in shutdown mode, the current consumption drops to 1μA.

6. Efficiency (η):

   • The typical efficiency of the device is 90%. This is achieved under normal operating conditions.

7. Switching Frequency (fSW):

   • The switching frequency is fixed at 1.2MHz. This helps in reducing the size of external components like inductors and capacitors.

8. Soft-Start Time (tSS):

   • The soft-start time is 2ms, which helps in reducing inrush current during startup.

9. Thermal Shutdown (TSD):

   • The device will shut down if the internal temperature exceeds 160°C to prevent damage.

10. Operating Temperature (TOPR):

    • The device is designed to operate within the temperature range of -40°C to 85°C.

11. Storage Temperature (TSTG):

    • The device can be stored within the temperature range of -40°C to 150°C without damage.

12. PCB Layout:

    • Use a good PCB layout with short traces and wide power planes to minimize parasitic inductance and resistance.
    • Place the input and output capacitors as close as possible to the device to ensure stable operation.

13. Inductor Selection:

    • Choose an inductor that can handle the maximum output current and has a low DC resistance to minimize losses.

14. Capacitor Selection:

    • Use high-quality ceramic capacitors for both input and output filtering to ensure stability and low ESR.

15. Thermal Management:

    • Ensure adequate heat sinking or use a thermally conductive pad on the back of the device to dissipate heat effectively.

By following these guidelines, you can ensure optimal performance and reliability of the FAN5068MP in your application.
