ADI ADUM5028-5BRIZ Low Emission Isolated DC To DC Converter

Product Description Of ADUM5028-5BRIZ

ADUM5028-5BRIZ 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.

ADUM5028-5BRIZ 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.

ADUM5028-5BRIZ isolated dc-to-dc converters provide a space saving 8 pin wide body SOIC.
