    hiiii....

    I am searching for a buck converter circuit whose input and output parameters are as follows

    when input is around 40v output should be around 15v
    when input is around 100v output should be around 35v

    so my buck converter range of operation will be as
    v in -- 35 to 100v
    v out -- 15 to 35v

    can any one please help me to design such a circuit...

    You know, a 3:1 step-down transformer would come very close to meeting your specs.

    Hey, this is just a continuation of your existing thread. You really shouldn't start multiple threads on the same topic.

    You might be able to use TL783 in your circuit. It's an adjustable step-down IC .There are examples in the datasheet, starting from page 10, that show you how to adjust the IC to your voltage.
