Description

With the advancements in artificial intelligence (AI) and machine learning (ML), enterprise servers have become power-intensive as these servers simultaneously process a large amount of data and storage. The steady-state power rating of each server motherboard has gone up 5kW to 6kW, in contrast to 1kW to 2kW for general servers. However, the form factor remains the same, imposing system design challenges due to increased power density. The load amplitude, slew-rate, and frequency of transient loads on AI servers have increased by three to four times compared to general servers. Considering these requirements, this reference design is developed using the LM5066I hot-swap controller to provide a robust and reliable input power-path-protection design in high-power server backplane systems with a nominal input voltage of 54V.
