Quad-Channel Isolator with Integrated DC-to-DC Converter Data Sheet ADuM5400 FEATURES GENERAL DESCRIPTION 1 isoPower integrated, isolated dc-to-dc converter The ADuM5400 device is a quad-channel digital isolator with Regulated 5 V output isoPower, an integrated, isolated dc-to-dc converter. Based on 500 mW output power the Analog Devices, Inc., iCoupler technology, the dc-to-dc Quad dc-to-25 Mbps (NRZ) signal isolation channels converter provides up to 500 mW of regulated, isolated power Schmitt trigger inputs with 5.0 V input and 5.0 V output voltages. This architecture 16-lead SOIC package with >7.6 mm creepage eliminates the need for a separate, isolated dc-to-dc converter in High temperature operation: 105C maximum low power, isolated designs. The iCoupler chip scale transformer High common-mode transient immunity: >25 kV/s technology is used to isolate the logic signals and the magnetic Safety and regulatory approvals components of the dc-to-dc converter. The result is a small form UL recognition factor, total isolation solution. 2500 V rms for 1 minute per UL 1577 The ADuM5400 isolator provides four independent isolation CSA Component Acceptance Notice 5A channels in two speed grades (see the Ordering Guide for more VDE certificate of conformity (pending) information). IEC 60747-5-2 (VDE 0884, Part 2) isoPower uses high frequency switching elements to transfer V = 560 V peak IORM power through its transformer. Special care must be taken APPLICATIONS during printed circuit board (PCB) layout to meet emissions RS-232/RS-422/RS-485 transceivers standards.
