Based on the iCoupler® and isoPower® chip scale transformertechnology, the ADM3260 is a hot swappable digital and powerisolator with two nonlatching, bidirectional communicationchannels, supporting a complete isolated I2C interface, and anintegrated isolated dc-to-dc converter, supporting up to150 mW of isolated power conversion.iCoupler is a chip scale transformer technology with functional,performance, size, and power consumption advantages ascompared to optocouplers. The bidirectional I2C channels eliminate the need for splitting I2C signals into separate transmitand receive signals for use with standalone optocouplers.Based on the Analog Devices, Inc., isoPower technology, theon-chip isolated dc-to-dc converter provides a regulated, isolatedvoltage of 3.15 V to 5.25 V with up to 150 mW of output power.With the ADM3260, the iCoupler and isoPower channels, alongwith the I2C transceivers, can be integrated with semiconductorcircuitry, which enables a complete isolated I2C interface andallows the power converter to be implemented in a small formfactor. The ADM3260 is available in 20-lead SSOP package andhas an operating temperature range of −40°C to+105°C.isoPower uses high frequency switching elements to transfer powerthrough its transformer. Special care must be taken during printedcircuit board (PCB) layout to meet emissions standards. See theAN-0971 Application Note for board layout recommendations
