Powering data centers: From the grid to the gate
Increasing needs of functionality and power level with limited spaces in server and telecommunication power supplies drive the adoption of wide-bandgap devices (including gallium nitride (GaN)), more accurate sensing circuits, and more complex real-time control. Our GaN, C2000™ microcontrollers, hall sensor, isolated amplifier products, and reference designs address the latest server and telecommunication power supply requirements including 80 Plus Titanium efficiency, Modular Hardware System-Common Redundant Power Supply (M-CRPS), and Open Compute Project Open Rack v3 (OCP ORv3) specifications. As data centers transition to liquid cooling solutions for high-density AI and high-performance computing workloads, our C2000 digital controllers enable precise thermal management, while our motor drivers optimize fan and pump control for efficient coolant circulation. Our comprehensive sensing portfolio, including temperature and humidity sensors, enables leak detection to ensure safe and reliable liquid cooling system operation.
