Background to Factorized Power Architecture

Supplying power to early electronics systems was relatively straightforward and could typically be accomplished with a single silver box AC-DC supply. However as system performance, power density and load voltage proliferation steadily increased, more sophisticated power systems architectures became necessary. This article looks at this evolution and introduces Factorized Power Architecture, which allows designers to meet the challenges of today’s high-performance electronics. Some History and Some Problems In the beginning, there was 5 V, and it was good. In the mid Eighties you could build a 19” VMEbus system with several MC68000 processor boards,...
