    Hi all,

    Can anyone provide me working feedback circuit for buck converter.
    Here output of buck is 13V.

    All you need is the feedback circuit?
    What about the rest of the circuit?

    Often one or two resistors will do the trick.

    You need to ask a more detailed question in order to obtain a helpful answer.

    Schematic diagram?

    What chip/controller are you using.

    I tested the feedback circuit with voltage divider. But it is not working perfectly.
    Controller used is dspic30f2010. Frequency for PWM is 50Khz.
    Circuit is synchrounous buck converter. Aim is to convert 24Vdc 100A to 12Vdc for load 500W.
