Instructions for Using FAN6756MRMY

1. Power Supply Connection:

   • Connect the input voltage (VCC) to the power supply within the operating range of 4.5V to 20V.
   • Ensure the ground (GND) is properly connected.

2. Output Configuration:

   • Set the desired output current by configuring the external components (inductor, capacitors, and feedback resistors).
   • The maximum output current is 1.2A.

3. Switching Frequency Adjustment:

   • Adjust the switching frequency using an external resistor (RT) connected to the RT/CLK pin.
   • The typical switching frequency can be set between 200kHz and 1200kHz.

4. Efficiency Optimization:

   • For optimal efficiency, ensure that the inductor and capacitor values are chosen to match the recommended values in the datasheet.
   • Efficiency is typically around 90% at full load.

5. Thermal Management:

   • Monitor the device temperature to ensure it does not exceed 160°C.
   • Use a heatsink or proper PCB layout to dissipate heat effectively.

6. Protection Features:

   • The device includes overcurrent protection, overvoltage protection, and thermal shutdown to prevent damage under fault conditions.
   • Ensure that these features are enabled and functioning correctly.

7. Shutdown Mode:

   • To enter shutdown mode, pull the EN/UVLO pin low.
   • The shutdown current is typically 1μA.

8. Layout Considerations:

   • Follow the recommended PCB layout guidelines to minimize noise and improve performance.
   • Keep high-current paths short and wide to reduce resistance and inductance.

9. Testing and Validation:

   • Test the circuit under various load conditions to ensure stable operation.
   • Validate the output voltage and current to meet the design specifications.
