Instructions for Use:

1. Power Supply Connection:

   • Connect the input power supply to the VIN pin and ensure it is within the specified input voltage range (4.5V to 28V).

2. Output Configuration:

   • Set the desired output voltage using external resistors connected to the FB (feedback) pin according to the datasheet formula.

3. Inductor Selection:

   • Choose an appropriate inductor value based on the load requirements and switching frequency to optimize performance.

4. Capacitor Selection:

   • Select input and output capacitors that can handle the ripple current and provide stable operation. Refer to the datasheet for recommended capacitor types and values.

5. Thermal Considerations:

   • Ensure adequate heat dissipation, especially at higher output currents, by providing a proper PCB layout with sufficient copper area or heatsink if necessary.

6. Layout Guidelines:

   • Follow good PCB layout practices to minimize noise and parasitic effects. Keep high-current paths short and wide, and place bypass capacitors close to the device.

7. Testing:

   • After assembly, test the circuit under various load conditions to ensure stability and correct output regulation.

For detailed specifications and more advanced configurations, refer to the official CR6850T datasheet provided by the manufacturer.
