Dear friends,

I just want to implement remote sensing in my LM5041 circuit. Can anybody share me the remote sensing circuit diagram?

Regards

    remote sense.docxH Aneesh,

    I sketched a circuit based on a 5V output for a voltage regulation loop using a 2.5V TL431. The basis of the circuit is that the power connection from Vout + and - to the load will carry the load current and will have a voltage drop due to the series resistance of the wire or PCB track. By using sense connections the voltage drop is eliminated as the sense wires doe not carry the load current and only carry a few mA's of sense current.
