Based on the iCoupler® and isoPower® chip scale transformer technology， the ADM32601 is a hot swappable digital and power isolator with two nonlatching， bidirecTIonal communicaTIon channels， supporTIng a complete isolated I2 C interface， and an integrated isolated dc-to-dc converter， supporTIng up to 150 mW of isolated power conversion. iCoupler is a chip scale transformer technology with functional， performance， size， and power consumption advantages as compared to optocouplers. The bidirectional I2 C channels eliminate the need for splitting I2 C signals into separate transmit and receive signals for use with standalone optocouplers. Based on the Analog Devices， Inc.， isoPower technology， the on-chip isolated dc-to-dc converter provides a regulated， isolated voltage of 3.15 V to 5.25 V with up to 150 mW of output power （see Figure 1）。 With the ADM3260， the iCoupler and isoPower channels， along with the I2 C transceivers， can be integrated with semiconductor circuitry， which enables a complete isolated I2 C interface and allows the power converter to be implemented in a small form factor. The ADM3260 is available in 20-lead SSOP package and has an operating temperature range of −40°C to+105°C. isoPower uses high frequency switching elements to transfer power through its transformer. Special care must be taken during printed circuit board （PCB） layout to meet emissions standards. See the AN-0971 Application Note for board layout recommendations..
