Inductors are used as the energy storage device in many switched-mode power supplies to produce DC current. The inductor supplies energy to the circuit to keep current flowing during the "off" switching periods and enables topographies where the …

A power inductor is used in a step-up, step-down, or step-up/step-down circuit to convert a certain voltage to the required voltage. Among those different circuits, it is primarily used in a type of circuit called a “switching regulator.”

THE FUNDAMENTALS OF POWER INDUCTORS TECHNICAL ARTICLES Data Sheet Dangers: An Illustration A key component of DC-DC converters, the power inductor has a significant impact on efficiency, transient response, overcurrent protection and physical size. Only with a clear picture of the pertinent inductor parameters can a user make an informed

Coilcraft’s leading power inductor technology meets the demand for high switching frequencies and small overall solution size in shielded composite core and traditional ferrite core constructions.

require power inductors mainly for battery-powered devices, embedded computing, and high-power/frequency DC/DC converters. It is essential to understand the electrical characteristics of inductors to design systems that are compact, cost-effective, efficient, and provide excellent thermal performance.

2024年11月7日 · Power inductors are a ubiquitous component in all portable and stationary consumer electronics extending from laptops to smart phones enabling sound power management. They are employed for noise handling and voltage level control modes for the operation of devices.

Power inductors are typically used for energy storage in DC/DC converters or high current noise filter applications, including motor speed control, adjustable lighting, DC power conditioning, and more. Power inductors can be divided further into two groups - shielded and unshielded. Unshielded power inductors have an open magnetic circuit

TDK has a widely varied lineup of power inductor products, and this article describes and explains effective methods for using power inductors, and key points for selecting them, according to the required characteristics of DC-DC converters.

Read this article to learn how to select the optimal inductor for a solution while predicting the inductor’s performance when designing a new DC/DC converter.

Understanding the fundamentals of power inductors is critical for both newer engineers and savvy veterans as they attempt to obtain performance data critical to their design. For various applications, inductor efficiency is often a major consideration in the design process.
