Eaton's CL family coupled inductors are commonly used in multi-phase topologies to take advantage of current ripple cancellation as well as a number of other significant benefits like higher efficiency and space savings. The CL family offers a number of foorprint options with up to 6 phases of coupling and either 50 nH or 100 nH of inductance per phase. Devices offered exclusively with voltage regulator employing power regulating devices manufactured by Maxim / Volterra
