為數據中心供電:從電網到閘極
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.

Engineering efficiency for rack power and thermal management

High-performance integrated GaN power stages

Our gallium nitride (GaN) power stages can help you achieve high efficiency and high density in your server power designs, and when leveraged to scale support high-voltage DC architectures. An integrated driver reduces circuit parasitics, which can help shrink design footprints.

With integrated overcurrent and overtemperature protection features, our power stages enable power-supply units, battery backup units and intermediate bus converter subsystems to achieve Modular Hardware System-Common Redundant Power Supply and Open Compute Project Open Rack v3 specifications.

Accurate and low-cost sensing

Current sensing plays a critical role in server and telecommunication power-supply units (PSUs). The control, protection and monitoring of various PSU subsystems requires accurate current measurements.

Our products for isolated current sensing include low-cost Hall-effect sensors and highly accurate shunt-based approaches for isolated sensing. For nonisolated sensing, our devices offer a wide range of supported voltages to help make current sensing easier.
