ADUM5242:  双通道隔离器,集成采用isoPower®技术的DC/DC转换器,提供50 MW隔离功率(0/2通道方向性)

产品详情

ADuM524x 均为集成isoPower隔离电源的双通道数字隔离器。芯片级DC/DC转换器基于ADI公司的iCoupler®技术,5 V电压时可提供最高50 mW稳压隔离功率,因而在低功耗隔离设计中,无需另外使用隔离式DC/DC转换器。利用ADI公司的iCoupler芯片级变压器技术,能够隔离逻辑信号和DC/DC转换器。因此,可提供小尺寸、完全隔离的解决方案。

ADuM524x隔离器提供两个独立的隔离通道,支持多种通道配置,输入工作电压为5 V。ADuM524x系列可以与其它iCoupler产品配合使用,以实现更多的通道数。

Solving Isolation Challenges in Power Conversion Applications
This webcast will present solutions to isolation challenges in power conversion applications. Among the topics to be discussed are the limitations of traditional methods of isolation (such as utilization of optocouplers and pulse transformers) vs. more efficient and cost effective solutions that utilize digital isolators. If you are currently using optocouplers and pulse transformers, this is a webcast you should attend.
