Instructions for Use:

1. Input Connection: Connect the input voltage within the specified range (4.5V to 28V) to the VIN pin. Ensure proper decoupling capacitors are placed close to the input pins.
2. Output Configuration: Set the desired output voltage using an external resistor network connected to the FB (feedback) pin. Refer to the datasheet for specific resistor values.
3. Output Capacitor: Place a suitable output capacitor at the VOUT pin to stabilize the output voltage. Recommended values typically range from 10μF to 47μF depending on load conditions.
4. Heat Management: Monitor the operating temperature and ensure it remains within the specified range (-40°C to +85°C). Use heat sinks if necessary.
5. Protection Circuits: The FIN1028MX includes built-in protection features such as overcurrent, overvoltage, and thermal shutdown. Ensure these features are not bypassed in the circuit design.
6. Layout Considerations: Follow good PCB layout practices, keeping high-current paths short and wide, and maintaining adequate clearance between components to minimize noise and interference.
