Skyworks - inductor currents

The Si882xx/Si883xx products have integrated digital isolator channels with an isolated dc-dc controller. This application note provides guidance for selecting the external components necessary for operation of the dc-dc controller.

Digital isolation applications with primary-side supply voltage of 3.0 V ≤ VIN ≤ 5.5 V and load power requirements of ≤ 2 W can use Si882xx/Si883xx products. The dc-dc controller in these products uses asymmetric half-bridge flyback circuit topology.
