Instructions for Using FAN73901MX

1. Power Supply Connection:

   • Connect the input voltage (V_IN) to the power supply within the specified range (4.5V to 26V).
   • Ensure that the input voltage is stable and free from excessive ripple or noise.

2. Output Configuration:

   • The output voltage (V_OUT) is typically set to 5V, but can be adjusted using external components if required.
   • Use appropriate output capacitors to stabilize the output voltage and filter out any high-frequency noise.

3. Current Limiting:

   • The device has an internal current limit to protect against overcurrent conditions.
   • If the load exceeds the maximum output current (1.5A), the device will enter a protection mode.

4. Thermal Management:

   • Monitor the temperature of the device to ensure it does not exceed the thermal shutdown temperature (160°C).
   • Use heatsinks or other cooling methods if necessary to maintain the device within its operating temperature range (-40°C to 125°C).

5. Shutdown Operation:

   • To put the device into shutdown mode, apply a low signal to the shutdown pin.
   • In shutdown mode, the device consumes minimal current (1μA).

6. Storage and Handling:

   • Store the device in a dry environment within the storage temperature range (-55°C to 150°C).
   • Handle the device with care to avoid damage from static electricity or mechanical stress.

7. Layout Considerations:

   • Place the device close to the load to minimize trace inductance and improve performance.
   • Use wide, short traces for power and ground connections to reduce resistance and inductance.

8. Testing and Validation:

   • Before finalizing the design, perform thorough testing to ensure the device meets all performance requirements.
   • Validate the design under various operating conditions, including extreme temperatures and load variations.
