ADI公司的DAuM5010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DAuM5010芯片的主要特性、方框图、应用方向。评估板EVAL-ADuM5010EBZ的主要特性、电路图、材料清单和PCB元件布局图。

The ADuM50101 is an integrated, isolated dc-to-dc converter. Based on the Analog Devices, Inc., iCoupler® technology, the dc-to-dc converter provides regulated, isolated power, adjustable between 3.15 V and 5.25 V. Input supply voltages can range from slightly below the required output to significantly higher. Popular combinations and their associated power levels are shown in  Table 1 .

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.

isoPower uses high frequency switching elements to transfer power through its transformer. Special care must be taken during printed circuit board (PCB) layout to meet emissions standards. See the AN-0971 Application Note for board layout recommendations.
