ADI ADuM6202 5KV隔离双路DC电源转换方案

ADI公司的ADuM6200/ADuM6201/ADuM62021是5KV隔离的双路DC/DC电源转换器和隔离器,包括了两路数字隔离器iCoupler和两路DC/DC转换器isoPower,5.0V输入时可提供绝缘输出5.0V或3.3V,功率高达400W,信号隔离是DC到25MHz(NRZ),主要用在RS-232/RS-422/RS-485收发器,工业现场总线隔离,电源起动偏压和栅极驱动,隔离的传感器接口以及工业PLC等.本文介绍了ADuM6200/ADuM6201/ADuM62021主要特性,方框图,以及EVAL-ADuMQSEBZ评估板主要特性,电路图,材料清单和评估板布局图.

The ADuM6200/ADuM6201/ADuM62021 are dual-channel digital isolators with isoPower®, an integrated, isolated dc-to-dc converter. Based on the Analog Devices, Inc., iCoupler® technology, the dc-to-dc converter provides up to 400 mW of regulated, iso-lated power at either 5.0 V or 3.3 V from a 5.0 V input supply, or at 3.3 V from a 3.3 V supply at the power levels shown in Table 1. These devices eliminate the need for a separate, isolated dc-to-dc converter in low power, isolated designs. The iCoupler chip scale transformer technology is used to isolate the logic signals and for the magnetic components of the dc-to-dc converter. The result is a small form factor, total isolation solution.
