ADUM5401WCRWZ-1

ADUM5401W is a quad-channel isolator with isoPower® integrated DC-to-DC converter. Based on the Analog Devices, Inc., iCoupler® technology, the dc-to-dc converter provides up to 500mW of regulated, isolated power at 5.0V. This device eliminates the need for a separate, isolated dc-to-dc converter in low power, isolated designs. The iCoupler chip scale transformer technology is used to isolate the 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. Safety and regulatory approvals are UL recognition: 2500V rms for 1 minute per UL 1577, CSA component acceptance notice 5A, VDE certificate of conformity, DIN EN 69747-5-2 (VDE 0884 Teil 2):2003-1, VIORM=565 V peak. Typical application is hybrid electric battery management.
