I am designing a buck converter. I have found an inductor to use for it but it consists of 4 pins. Will I not need only 2 pins? The inductor is: WURTH ELEKTRONIK 7446622002 CHOKE, COMMON MODE, 2.2MH, 2A.
Heres the link to datasheet:http://www.farnell.com/datasheets/1735935.pdf
Can you please tell me how can i use (which pins to connect) this inductor for my application?
