ADUM5241: 双通道隔离器,采用isoPowerTM 技术,内部集成DC-DC转换器,功耗50 mW
The ADuM524x* are dual-channel digital isolators with isoPower integrated, isolated power. Based on the Analog Devices, Inc. iCoupler(R) technology, a chip-scale dc-to-dc converter provides up to 50 mW of regulated, isolated power at 5 V, which eliminates the need for a separate isolated dc-to-dc converter in low power isolated designs. The Analog Devices chip-scale transformer iCoupler technology is used both for the isolation of the logic signals as well as for the dc-to-dc converter. The result is a small form factor, total isolation solution.
The ADuM524x isolators provide two independent isolation channels in a variety of channel configurations, operating from a 5 V input supply. ADuM524x units may be used in combination with other iCoupler products to achieve greater channel counts.
