Overview
The ADUM5404ARWZ-RL from Analog Devices Inc. is a quad-channel digital isolator that integrates an isolated DC-to-DC converter using the isoPower® technology. This device is designed to eliminate the need for a separate isolated DC-to-DC converter in low-power, isolated designs. It utilizes the iCoupler® chip scale transformer technology to isolate logic signals and power/feedback paths, resulting in a compact, total isolation solution. The isoPower converter transfers power through high-frequency switching elements and is certified by various regulatory bodies including UL, CSA, VDE, and CQC.
