A polyphase digital controller (digital multiphase controller) is a digital power management IC that coordinates multiple parallel buck converter phases to deliver high, regulated current from a higher DC input (e.g., 12V) to a low‑voltage load (e.g., 0.8–1.8V). It uses digital signal processing to ensure balanced current sharing, fast transient response, adaptive phase shedding, and programmable protection/telemetry.
Application Scope：
1.Server&Data Center VRMs:Powering high‑current CPUs/GPUs/SoCs(100–800A).
2.High‑Performance Computing(HPC)&AI Accelerators:500W+rails for AI chips.
3.Telecom&Networking:48V/12V distribution to low‑voltage ASICs/FPGAs.
4.Industrial&Embedded:High‑efficiency,scalable power for industrial PCs and robotics.
5.Automotive:High‑current,rugged power for ECUs and infotainment systems.
