[原创]ADI ADuM4223 5KVrms绝缘4A输出半桥驱动器解决方案

ADI公司的ADuM4223是5KVrms绝缘4A输出半桥驱动器,高边或低边相对于输入565VDC峰值,工作频率最高1MHz,CMOS输入逻辑3.3V-5V,输出驱动4.5V-18V,主要用在开关电源,绝缘IGBT/MOSFET栅极驱动和工业逆变器.本文介绍了ADuM3223/ADuM4223主要特性,功能框图,评估板EVAL-ADuM4223AEBZ主要特性,电路图,材料清单和PCB布局图.

The ADuM3223/ADuM4223 provides 3000 V rms isolation in the narrow body, 16-lead SOIC package, and the ADuM4223 provides 5000 V rms isolation in the wide body, 16-lead SOIC package. Combining high speed CMOS and monolithic transformer technology, these isolation components provide outstanding performance characteristics superior to the alternatives, such as the combination of pulse transformers and gate drivers. 1 are 4 A isolated, half-bridge gate drivers that employ the Analog Devices, Inc., iCoupler® technology to provide independent and isolated high-side and low-side outputs.
