Powering the Next Generation of Data Centers
AI data centers demand power systems that are efficient, resilient and built for continuous operation. Our dsPIC33 Digital Signal Controllers (DSCs) are purpose-built for real-time digital power control, which helps accelerate high-density server power designs with fast digital control loops, high-efficiency power delivery, advanced multilevel power topology support and long-term embedded security.
Through software-defined control architectures, optimized Power-Factor Correction (PFC) and DC-DC control methodologies for mCRPS power supply designs, high-resolution Pulse-Width Modulation (PWM) and fast analog feedback, dsPIC33 DSCs enable precise and responsive power conversion. They also support live firmware updates for always-on performance, secure boot, authenticated Over-The-Air (OTA) updates and Post-Quantum Cryptography (PQC)-ready security, all within model-based design workflows. Backed by expert power design resources and more than 20 years of experience in power supplies, we provide the technology and support needed to develop reliable, secure, and scalable power solutions for next-generation data centers.
