Part details & applications

The ADuM5028 is an isoPower^®, integrated, isolated dc-to-dc converter. Based on the Analog Devices, Inc., iCoupler^® technology, the dc-to-dc converter provide regulated, isolated power that is below CISPR22 Class B limits at full load on a 2-layer PCB with ferrites.

The ADuM5028 eliminates the need to design and build an isolated dc-to-dc converter in 300 mW applications. The iCoupler chip scale transformer technology is used for the magnetic components of the dc-to-dc converter. The result is a small form factor, isolated solution.

The ADuM5028 isolated dc-to-dc converters provide a space saving 8 pin wide body SOIC.

Applications

RS-485/RS-422/CAN transceiver power
Power supply startup bias and gate drives
Isolated sensor interfaces
