AN-2592: Inductor Selection Guide for Home Bus System

Overview

TopologyOther Topology

Description

In a two-wire Power over Data (PoD) application such as the Home Bus System, an “AC-blocking” inductor is used to separate the data signals from the DC power. Selecting a suitable inductor is critical in designing the communication network. This application note outlines the inductor selection standards for the application and how to qualify the choice of inductors.
