Design considerations
- The motherboard hosts, powers and interconnects processors, memory, storage and networking, requiring efficient power distribution and high signal integrity across dense layouts
- AI accelerators can be deployed on dedicated trays or connected via PCIe, requiring scalable power delivery and robust high-speed interconnect support
- Supply rails typically range from 12 V, 48 V or 54 V, with future systems moving toward 400 V and 800 V to improve distribution efficiency in high-power racks
- Power input protection must address surge, reverse polarity and inrush current using TVS diodes, ideal diodes, eFuses and hot-swap controllers, protecting both the server and the supply
- Power management requires multiple high-efficiency DC-DC converters with integrated switching to generate accurate voltage rails for processors and peripheral components
- Communication interfaces require low-capacitance ESD protection to maintain signal integrity, while buffers and transceivers support longer traces and reliable board-to-board communication
