ADUM6423ABRNZ5

ADUM6423A is a quad-channel digital isolator with an isoPower®, integrated, isolated dc-to-dc converter. Based on the Analog Devices, Inc., iCoupler® technology, the dc-to-dc converter provides regulated, isolated power that meets CISPR 32/EN 55032 Class B limits at a full load on a 2-layer printed circuit board (PCB) with ferrites. This device eliminate the need for a separate, isolated dc-to-dc converter in 500mW, isolated designs. The iCoupler chip scale transformer technology is used for isolated logic signals and for the magnetic components of the dc-to-dc converter. The result is a small form factor, total isolation solution. It is approved by 5000V rms for 1 minute per UL 1577, VIORM = 566V peak. It is used in application such as RS-232 transceivers, power supply start-up bias and gate drives, isolated sensor interfaces, automotive on-board charger (OBC) and dc to dc, industrial programmable logic controllers (PLCs) etc.
