en.Wedoany.com Reported - Today, South Chip Technology (Stock Code: 688484) proudly announces the launch of the 22V/60A high-current DrMOS SD13050 and the dual-channel four-phase controller SD22442, providing efficient and reliable power supply solutions for computing chips such as CPUs, GPUs, and SoCs. Both products are available in industrial-grade and automotive-grade versions certified to AEC-Q100 Grade 1, covering a wide range of computing scenarios from data centers and edge servers to autonomous driving.
Computing Power Surge Drives Blue Ocean Growth in Multi-Phase Power Supplies
Currently, AI computing power construction has entered an explosive phase. The rapid iteration of scenarios such as large model training, autonomous driving, and industrial intelligent connectivity has led to exponential growth in computing power demand. According to institutional forecasts, global AI server shipments are expected to reach approximately 3.7 million units in 2026, a year-on-year increase of 51.3%.
The AI computing power boom not only drives a surge in chip power consumption but also multiplies current demands. Against this backdrop, the low-voltage, high-current solution combining multi-phase controllers and DrMOS, with its ability to support higher currents, superior transient response, and greater efficiency, has become the mainstream power supply technology for high-performance computing chips. It is expected to penetrate from high-end servers to general-purpose AI servers and edge computing, ushering in broader development opportunities.
Efficient Power Supply Solution for CPUs/GPUs
DrMOS integrates the driver and power MOSFET into a single package using co-packaging or single-die technology, offering advantages such as smaller size, lower parasitic parameters, faster switching speeds, and reduced losses. It also simplifies PCB layout and enhances thermal management performance, making it particularly suitable for high-density power applications with stringent space and efficiency requirements. Among these, the single-die solution facilitates future integration of VRM packaging modules in vertical power architectures, reserving greater evolution space for the power supply form of next-generation computing chips. By paralleling multiple DrMOS units, the current capacity for computing chips increases linearly, but this comes with exponentially growing control complexity. The multi-phase controller is the core to addressing this challenge, responsible for communicating with the main chip and dynamically adjusting the output of each phase to achieve precise coordinated control of the entire power supply system.
South Chip Technology's CPU/GPU Efficient Power Supply Solution (SD13050 + SD22442) supports a 5V-16V input bus and dual voltage rail outputs, with flexible phase configuration per rail to meet design requirements for different power levels. The SD22442 supports DCM (Discontinuous Conduction Mode) and APS (Active Phase Shedding) functions, which, combined with the high-precision ZCD current sensing of the SD13050, significantly optimize system efficiency under light-load conditions.
DrMOS SD13050
As the energy conversion core of the entire solution, the SD13050 delivers up to 60A of continuous output current within an ultra-compact 5mm*6mm LGA package, maintaining high efficiency across the full load range while offering high-precision sensing and comprehensive protection mechanisms. Through optimized dead-time control and parasitic inductance suppression design, the SD13050 ensures high system efficiency under all load conditions. Additionally, the SD13050 integrates high-precision inductor current sensing and temperature sensing functions, providing real-time fault protection data for the four-phase controller. Its built-in rich protection mechanisms effectively prevent excessive discharge of the bootstrap capacitor, ensuring system reliability during high-frequency operation.
Dual-Rail Four-Phase Digital Controller SD22442
The SD22442 serves as the command center of the solution, housed in a 6mm*6mm QFN package, supporting flexible configuration of up to four phases across two independent voltage rails. Its core competitiveness lies in comprehensive digital control capabilities and extensive interface compatibility: it supports both PWMVID and PMBus communication protocols, allowing flexible adaptation to power management specifications of different processor platforms; it features built-in MTP memory for secure storage and recall of user-defined configurations. The automotive-grade version SD22442Q complies with ISO 26262 ASIL-B functional safety levels, providing robust assurance for autonomous driving systems with stringent safety requirements.
South Chip Technology's Computing Power Product Family
As AI computing power continues to descend from the cloud to the edge and terminals, and as autonomous driving levels advance, the demand for high-current, high-dynamic power supply will become a long-term necessity for computing chips. The combined solution of South Chip Technology's SD13050 and SD22442, with its complete power architecture, flexible dual-rail configuration, and automotive-grade safety assurance, provides a solid technical foundation for this trend. Looking ahead, South Chip will continue to deepen its focus on high-power-density power management, leveraging a more comprehensive product portfolio to support the energy efficiency upgrade of global computing infrastructure.
The SD13050+SD22442 CPU/GPU Efficient Power Supply Solution will be showcased at the South Chip booth (Hall N4, Booth N4.608) at the Munich Shanghai Electronics Show. We warmly welcome everyone to visit and engage with us!
