Significant disruption occurs when a PDN, based on an industry standard such as 12 volts, can no longer meet the demands in system power. With this disruption comes a great opportunity for power-system designers to innovate PDNs based on a new standard such as 48V. 48V is emerging in hybrid vehicles, data centers, artificial intelligence (AI) accelerator cards, LED displays and unmanned vehicles. As industries transition to new PDNs, advanced power-delivery architectures and modular power components should be considered as a way to substantially improve end-system performance and design a long-term, flexible and scalable PDN.
