ADI DAuM5211隔离DC－DC控制器参考设计方案

ADI公司的DAuM5211是一款双通道内部集成数字隔离DC-DC转换控制器。基于ADI公司先进iCoupler® 技术，数字隔离DC-DC转换控制器提供隔离调整电压范围：3.15-5.25V，输入电压的范围可以从供给略低于所需的输出来显著提高。本文介绍了DAuM5211芯片的主要特性、方框图、应用方向。评估板EVAL-ADuM5211EBZ的主要特性、电路图、材料清单和PCB元件布局图。

The ADuM5210/ADuM5211/ADuM52121 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 regulated, isolated power that is adjustable between 3.15 V and 5.25 V. Input supply voltages can range from slightly below the required output to significantly higher. Popular voltage combinations and their associated power levels are shown in  Table 2 .

The ADuM5210/ADuM5211/ADuM5212 eliminate the need for a separate, isolated dc-to-dc converter in low power, isolated designs. The iCoupler chip-scale transformer technology is used for isolated logic signals and for the magnetic components of the dc-to-dc converter. The result is a small form factor, total isolation solution.
