Optimization of the Power Supply Architecture Comes First

Technical Article Overview 

Before component selection or circuit simulation begins, engineers must define the right power supply architecture. In systems requiring multiple voltage rails, early power tree decisions can significantly affect efficiency, cost, size, and design complexity.

This technical article from Analog Devices introduces power supply architecture planning using LTpowerPlanner within the LTpowerCAD tool chain. It explains how engineers can sketch power trees, calculate system-level efficiency across alternate architectures, and weigh trade-offs like using a linear regulator instead of an additional switching converter to balance cost against performance before moving into detailed circuit design.
