Power Distribution Solutions for Densely-Populated PCBs

As electronic PCBs become more densely packed and supply rail voltages proliferate, delivering the right power to all on-board devices with optimal space and power efficiency becomes essential. This article looks at developments in power distribution architecture and device technology that allows designers to achieve this optimization. As the electronics industry has developed, some inexorable trends have become apparent. Boards decrease in size and become more densely populated. Supply voltages demanded by on-board IC devices such as CPUs, DSPs, FPGAs, logic and memory have proliferated and there is a tendency towards lower levels such...
