面向48V数据中心的共地Sigma变换器系列

The 48 V bus architecture has become a standard in modern data centers, due to the increasing power demands of digital loads. This requires low-profile, high-density intermediate bus converters, able to efficiently step-down the input bus. Usually, this bus has a wide variation (40–60 V), and the voltage regulation module (VRM) must withstand the whole converted range, with a negative impact on ef...
