"WebSep 10, 2007 · While designing a buck converter, there is always a trade-off between the inductor and the capacitor size selection. A larger inductor value means numerous turns to the magnetic core, but less ripple current (<10% of full load current) is seen by the output capacitor; therefore, the loss in the inductor increases. Also, less ripple current " - Buck inductor loss
