Product ADUM3474ARSZ is a quad-channel digital isolator with advanced features that make it a versatile and efficient solution for isolated DC/DC converter applications. By integrating a PWM controller and transformer driver, this device eliminates the need for a separate isolated DC/DC converter in designs requiring up to 2 W of regulated, isolated power. The iCoupler technology from Analog Devices, Inc. ensures reliable isolation of logic signals, while the chip-scale transformer technology enables higher efficiency for the DC/DC converter
