Power Modules and Devices to Support Intermediate Bus Architecture Designs
By Steve Taranovich, Electronic Products
Almost three decades ago, the “brick” DC/DC converter power module was developed, which eventually led to the distributed power architecture (DPA) becoming the de facto standard for point of load (POL) designs. Soon, cost and board footprint became an issue and designers searched for alternative solutions for their power management architectures.
This article will discuss one of the more recent and popular power architectures emerging as a solution to designers’ problems, the intermediate bus architecture (IBA).
