Instructions for FAN7320BO:

1. Power Supply Connection:

   • Connect the input voltage (VIN) between 4.5V and 20V to the appropriate pins.
   • Ensure a stable power source to avoid fluctuations that could affect performance.

2. Output Configuration:

   • The output voltage is preset to 17V in boost mode, but can be adjusted using external components if necessary.
   • Verify the output voltage with a multimeter before connecting any load.

3. Frequency Adjustment:

   • Adjust the switching frequency within the range of 200kHz to 1000kHz using an external resistor or as specified by the application requirements.

4. Load Management:

   • Do not exceed the maximum load current of 3A to prevent damage to the device.
   • Use appropriate heat sinking if operating near the maximum load conditions.

5. Thermal Considerations:

   • Monitor the operating temperature to ensure it remains below 160°C to prevent thermal shutdown.
   • Provide adequate ventilation or cooling if operating in high-temperature environments.

6. Shutdown Mode:

   • To enter shutdown mode, pull the enable pin low. This will reduce the current consumption to approximately 0.1μA.
   • Ensure the enable pin is properly managed to avoid unintended shutdowns.

7. Environmental Conditions:

   • Operate within the temperature range of -40°C to 85°C for optimal performance.
   • Avoid exposing the device to extreme temperatures outside this range.
