Developing the optimum power architecture for a new circuit board design with point-of-load (PoL) DC-DC power modules should be a methodical, objective process involving a thorough analysis of technical tradeoffs and predictive analytics of performance. The task becomes even more daunting as the increasing complexity of board designs increases the number of PoL power rails present in many of today’s designs. This paper covers the significance of design tools that offer comprehensive power design environments, complete with the simulation and modeling capabilities that enable engineers to quickly focus on solutions for their technical requirements.
