ADUM5028-3BRIZ

ADUM5028 is an isoPower®, integrated, isolated dc-to-dc converter. Based on the Analog Devices, Inc., iCoupler® technology, this dc-to-dc converter provides regulated, isolated power that is below CISPR22 Class B limits at full load on a 2-layer printed circuit board (PCB) with ferrites. It eliminate the need to design and build isolated dc-to-dc converters in applications upto 500mW. 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. It is widely used in application such as RS-485/RS-422/CAN transceiver power, power supply start-up bias and gate drives, isolated sensor interfaces, industrial PLCs.
