A buck converter is a type of switching regulator which we use to step down a high DC voltage to a lower DC voltage. The inductor is a very important part of the circuit because it stores and releases energy to keep output power

In this example, the total inductor power loss is 0.294W + 0.983W = 1.277W. There are many inductor types to choose from, but most buck DC/DC converters typically use ferrite drum and iron powder toroid inductors. So when designing a buck converter, keep these inductor selection criteria in mind for a high-performance, stable and reliable design.

The inductor value can be increased to reduce the ripple-ratio; however, this will typically result in an inductor size that is physically too big for practical use. Consequently, “r” is usually set between 0.2 and 0.5 for buck converters. or Current flowing through the coil is a combination of output current and ripple-current.
Synchronous Buck DC/DC Converter You should select inductors to manage output capacitor size, load transients and output ripple current. There are benefits of both low and high inductance values. Lower DC resistance (DCR), which is inherent in the inductor wire, and which affects ripple and power loss.
