Instructions for Using the FSFR2100XSL

1. Input Connection:

   • Connect the input voltage (V_IN) to the VIN pin.
   • Ensure the input voltage is within the range of 4.5V to 36V.

2. Output Configuration:

   • Set the output voltage (V_OUT) using external resistors or a fixed voltage divider.
   • The output voltage can be adjusted from 0.8V to 36V.

3. Load Connection:

   • Connect the load to the VOUT pin.
   • The maximum continuous output current is 3A, with a typical output current of 2A.

4. Switching Frequency:

   • The switching frequency is typically 600kHz, which helps in reducing the size of external components like inductors and capacitors.

5. Efficiency:

   • The converter has a typical efficiency of 92%, ensuring minimal power loss during operation.

6. Quiescent Current:

   • The quiescent current is typically 35渭A, making it suitable for low-power applications.

7. Shutdown Mode:

   • Use the SHDN pin to control the shutdown mode. When the SHDN pin is pulled low, the shutdown current is reduced to 0.1渭A.

8. Thermal Considerations:

   • Ensure proper heat dissipation by mounting the device on a heatsink or PCB with good thermal conductivity.
   • The operating temperature range is from -40掳C to 125掳C, and the storage temperature range is from -65掳C to 150掳C.

9. Capacitor Selection:

   • Choose input and output capacitors that can handle the ripple current and provide stable operation.
   • Recommended input capacitor: 10渭F to 100渭F ceramic.
   • Recommended output capacitor: 10渭F to 100渭F ceramic or tantalum.

10. Inductor Selection:

    • Select an inductor with a value that ensures stable operation at the desired output current and switching frequency.
    • A typical inductor value is 4.7渭H to 10渭H.

11. PCB Layout:

    • Follow good PCB layout practices to minimize noise and ensure reliable operation.
    • Keep the input and output capacitors close to the IC.
    • Use wide traces for high-current paths.

12. Testing and Validation:

    • Test the circuit under various load conditions to ensure stability and performance.
    • Monitor the temperature of the IC and surrounding components to ensure they remain within safe operating limits.
