dc dc converter inductor
I was trying to design a switching DC-DC converter and I face an initial current of more than 2 A through the inductor coil in the simulation. Though this is for a very short time of 30 usec and very rapidly decreases to 0.25 mA at 50 usec after 30 usec peak value. I doubt whether that current spoils the coil. I tried to go through the specification sheets of some famous coils vendors like MURATA but the absolute maximum current is not specified clearly though they specified DC maximum current for temperature rise and Inductor value change.
Can anybody help me in this case??
