The rapid development of artificial intelligence (AI) has ushered in a new era of high-density computing demands, and traditional power supply architectures are gradually struggling to adapt to this evolving demand. To better respond to such demands, Analog Devices, Inc. (ADI) has launched innovative solutions to provide robust support for the next-generation 800 VDC architecture in data centers. This series of solutions includes high-reliability hot-swappable and primary power supply products, designed to achieve safe, efficient, and intelligent power distribution, precisely meeting the power supply needs of modern AI factory systems.

Why choose 800V architecture?

Data centers are transitioning from traditional 12 V or 48 V systems to 800 V architectures, with the core reason being to achieve large-scale energy efficiency upgrades. Faced with the high power demands of AI clusters, elevating the voltage to 800 V enables a qualitative leap in computing cluster density, with rack power density even reaching or surpassing 1 MW.

Todd Sherman, General Manager of ADI's High Voltage and Protection Business, stated, "ADI is proud to be driving the development of 800 V high-voltage data center architecture technology. ADI holds a leading position in the field of hot-swap controllers, and these products have become an indispensable key component for protecting new AI systems.". ”

ADI hot-swap controller: safeguarding the safety of high-power systems

The core function of hot-swap controller ICs is to protect the system from sudden changes in power supply, while ensuring continuous and stable operation. In AI factories, the role of such controllers is particularly crucial - whether during system startup, malfunction, or maintenance, they can effectively manage surge currents, establishing a robust safety barrier for high-voltage power supply systems.

With its proven chip technology and extensive expertise in high-voltage analog design, Analog Devices (ADI) holds a leading position in providing critical protection mechanisms for systems.

The ADI 800 V series solution can facilitate the achievement of the following core guarantees:

· Controlled power-on of AI racks: Effectively suppress the generation of current spikes when the rack is plugged in, avoiding damage to downstream converters.

· Real-time fault detection: Supports precise telemetry monitoring and system diagnostic functions, while ensuring safe operation under fault conditions.

· 99.99% redundancy and resilience: For an AI factory that operates continuously 24/7, this characteristic is crucial for ensuring the system's uninterrupted operation.

Practical application of 800 V architecture

After the 800 V power supply is smoothly connected to the rack, it needs to be converted to an intermediate voltage (usually 48 V or lower) through voltage reduction, and then undergo local voltage regulation to supply power to the processor, GPU, and accelerator.
