Instructions for Using the FAN5236QSCX

1. Power Supply Connection:

   • Connect the input voltage (VIN) to the power supply within the specified range (2.7V to 5.5V).
   • Ensure proper bypass capacitors are placed close to the VIN and GND pins to filter out noise and stabilize the input voltage.

2. Output Configuration:

   • The output voltage (VOUT) is fixed at 1.8V. If a different output voltage is required, use external resistors to adjust the feedback network.
   • Place a ceramic output capacitor (typically 10μF to 22μF) between VOUT and GND to ensure stability and reduce output ripple.

3. Thermal Management:

   • Ensure adequate heat dissipation by using a PCB with a thermal pad connected to the exposed pad on the bottom of the QFN package.
   • Avoid operating the device in environments where the ambient temperature exceeds 85°C to prevent thermal shutdown.

4. Shutdown Control:

   • To shut down the device, pull the EN (Enable) pin low. The device will enter a low-power mode with minimal current draw.
   • To activate the device, pull the EN pin high (VIN or a logic high signal).

5. Protection Features:

   • The device includes short-circuit protection, which limits the output current during a short circuit and automatically recovers after the fault is cleared.
   • Thermal shutdown protects the device from overheating and will automatically restart once the temperature drops below the threshold.

6. Layout Considerations:

   • Keep the traces between the input and output capacitors as short as possible to minimize parasitic inductance.
   • Use wide traces for power and ground connections to reduce resistance and improve thermal performance.

7. Testing and Validation:

   • Before finalizing the design, perform load tests to ensure the device meets the required performance specifications under all operating conditions.
   • Verify the output voltage accuracy and stability using an oscilloscope and multimeter.

By following these guidelines, you can ensure optimal performance and reliability of the FAN5236QSCX in your application.
