I have a DC supply of 72V Li-ion battery. The maximum supply voltage with spike may go 72+10V. I need 15V of output voltage with a current of 1-2A. Please suggest me how to approach this design & which are the IC's available to design in a cost effective manner. Hoping to get some help.

    Hello,

     

    For this aaplication you might start with the LM5116 device.   There is an evaluation board that is set up for 12V output that could possibly be modified.
