Overview
The ADUM5400ARWZ-RL, produced by Analog Devices Inc., is a quad-channel digital isolator that integrates an isolated dc-to-dc converter using the iCoupler® technology. This component provides up to 500 mW of regulated, isolated power with 5.0 V input and 5.0 V output voltages. The integrated dc-to-dc converter eliminates the need for a separate isolated power supply in low-power, isolated designs. The device features a secondary side controller architecture with isolated pulse-width modulation (PWM) feedback, ensuring high power efficiency and stability. It is designed for applications requiring high common-mode transient immunity and strict safety and regulatory compliance.
