New Application Note - TLVR Inductors: The Basics and How They Improve Multiphase DC-DC Converters

Abracon is excited to announce the release of our guide to TLVR inductors, “TLVR Inductors: The Basics, and How They Improve Multiphase DC-DC Converters.” This article offers a deep dive into the fundamental principles of trans-inductor voltage regulator (TLVR) inductors and their crucial role in enhancing the performance of multiphase DC-DC converters.

Traditional DC-DC Converters and Their Drawbacks

We begin this new application note by going over conventional DC-DC converters and their disadvantages. Traditional multiphase DC-DC converters, while effective, often face challenges in responding swiftly to sudden changes in load. As demand surges, the control system must sequentially adjust each phase, leading to delays in meeting the new current requirements. The TLVR topology seeks to minimize these response times by optimizing how each phase is triggered, resulting in a faster, more efficient power delivery solution.

How TLVR Works

At the heart of TLVR designs lies the utilization of TLVR inductors, which resemble transformers, as output inductors for each phase. The magnetic coupling between the primary and secondary ensures not only one but all phases respond to the demand instantaneously. (Read more)
