Continued demand for Artificial Intelligence (AI) services in High-Performance Computing (HPC) data centers is driving the market growth in this segment. Special-purpose AI accelerators facilitate a significant increase in the performance and efficiency of these data centers. Like in many critical infrastructure systems, reliability and high availability are essential and highly challenging. Developers of AI supercomputing platforms can only address these requirements with hot-swap solutions that monitor the power supply and protect the system even when components are hot-swapped.
Infineon Technologies AG tackles these challenges by introducing the XDP™ XDP710 digital controller, the first member of its intelligent hot-swap controller and protection IC family. The hot-swap and system monitoring controller IC has a 5.5 V to 80 V input voltage range with transients up to 100 V for 500 ms. It consists of three functional blocks. The first is the high-precision telemetry and digital safe operating area (SOA) control block, optimized to meet Infineon’s power MOSFETs characteristics. The second is the system resources and management block, and the third is the integrated gate driver and charge pump block for n-channel power MOSFETs such as OptiMOS™ and StrongIRFET™ families.
The key feature of the XDP710 controller is its advanced closed-loop SOA control and the fully digital operating mode. This leads to a lower bill-of-material (BOM) reducing the number of external components and design time, allowing faster time-to-market. The XDP XDP710 can also operate in Analog-Assisted Digital Mode to support legacy systems.
