Here’s a professional English translation of the Chinese title: **”3PEAK’s Full-Stack Analog Chip Solution for AI Data Centers: Building a Solid Foundation for Intelligent Computing”**

Leveraging its deep technical expertise in high-performance analog chips and a comprehensive product portfolio, 3PEAK has developed a complete analog chip solution for AI data centers, covering core computing units, data center power systems, and AIDC backup power BMS systems. Currently, 3PEAK serves over a hundred leading customers in mainstream AI servers, power modules, and energy storage backup sectors both domestically and internationally, achieving rapid revenue growth in the AI and data center fields, and is becoming a core supply force for domestic analog chips in the era of intelligent computing.

An AI data center is a complex system integrating computing power, power supply, and security protection. Its operational efficiency, stability, and safety directly determine the quality and continuity of intelligent computing services, making it crucial for the efficient operation of digital infrastructure. Analog chips serve as the “invisible cornerstone” ensuring the smooth operation of each component.

Core Computing Unit
Full-stack solution ensures efficient and stable operation of the computing engine

The core computing unit is the “computing engine” of an AI data center, encompassing CPU/GPU/AI accelerator chip clusters, memory support, board-level signal processing, and power distribution networks. Its primary responsibility is to maximize computing efficiency. This scenario imposes extremely stringent requirements on analog chips: ultra-high precision power supply monitoring, nanosecond-level signal response, extremely low noise interference, and long-term stability for 7×24-hour full-load operation. Even millivolt-level power fluctuations can cause computing chips to throttle, lead to operational anomalies, or even system crashes.

Detection and protection are vital for the stable operation of server motherboards. 3PEAK’s AFEs, ADCs, CSAs, comparators, and temperature sensors have been deeply embedded in the server industry for years, with mature application scenarios. In response to the 48V/54V high-voltage power supply requirements of AI servers, 3PEAK has specifically launched the TPA6271 AFE product for high common-mode voltage power detection and the TPA132 series CSA current-sense amplifier products, adapting to high-voltage power supply scenarios and building the first line of defense for stable server operation.

TPA6271 integrates a 16-bit ADC, supports a wide input voltage range of 0V to 102.4V, with a maximum offset voltage of ±10μV and a temperature drift of 0.025μV/℃. Optimized for high-precision current detection, it is specifically designed for high common-mode voltage power detection in AI server 48V/54V high-voltage input power supplies.

TPA183Ax is a high-precision, zero-drift CSA current-sense amplifier supporting a wide common-mode voltage range of 2.7V to 30V, with an offset voltage as low as 55μV. It offers four selectable fixed gains: 25V/V, 50V/V, 100V/V, and 200V/V, enabling accurate detection of current in the power bus.

TPA132Ax is a high common-mode voltage CSA current-sense amplifier supporting an ultra-wide common-mode voltage range of -4V to 80V and a high bandwidth of 1MHz. It also integrates enhanced PWM rejection capability, making it perfectly suitable for precise current detection in AI server 48V/54V high-voltage input scenarios.

Power management is the power source driving efficient server operation, requiring multi-rail differentiated power supply for the motherboard. 3PEAK has launched products such as POLs, LDOs, eFuses, power sequencing controllers, and power monitors, providing efficient and stable power solutions for server motherboards, helping the computing engine deliver sustained output.

TPP21206 adopts a self-developed fixed-frequency ACOT control architecture. While retaining the advantages of traditional COT control, it achieves a fixed operating frequency under varying input voltage (Vin), output voltage (Vout), and load conditions. Thoroughly tested across different duty cycles and full load conditions, the frequency remains stable under various operating scenarios, addressing the instability issue of COT architectures and significantly improving transient response and output ripple.

Interface chips serve as the “communication bridges” for interconnecting devices within the server. 3PEAK has built a complete I2C/I3C interface chip solution, comprehensively covering full-function scenarios including IO expansion, multi-master arbitration, multi-channel signal switching, hot-swap, level shifting, and signal repeating, breaking down barriers to device interconnection.

TPT29606 is a level shifter chip launched by 3PEAK for I3C applications. It can transmit both open-drain and push-pull signals, compatible with I2C and SPI scenarios. It supports a minimum supply voltage of 0.72V and a maximum data rate of 26Mbps, widely used in servers, routers, storage, PCs, and other fields.

Signal processing chips enable multi-channel signal switching, long-distance signal driving, level shifting, and logic function combination. 3PEAK has a complete logic product matrix, covering AHC, LVC, AUP, AVC, and other series, offering 2-8 bit fixed-direction and auto-direction level shifters, fully adapting to various signal processing needs in servers, ensuring accurate, efficient, and distortion-free signal transmission.
